Don’t look up! Apocalypse-level asteroid to fly past Earth this month

AARON REICH – January 3, 2022

A massive kilometer-sized asteroid is set to fly past the Earth later this month in what is set to be the first flyby of an asteroid of this size during 2022, according to NASA’s asteroid tracker. This asteroid could cause a worldwide cataclysm if it impacted Earth, but this is thankfully extremely unlikely to happen.

Dubbed 7482 (1994 PC1), this asteroid has an estimated diameter of at least 1 kilometer, and could possibly be around 1.3 kilometers wide. For comparison, that’s over four times the size of the Eiffel Tower and 3.5 times the size of New York City’s Empire State Building.

The asteroid is categorized as an Apollo-class asteroid, meaning its orbit is wider than Earth’s and its orbital path around the Sun can cross the path of our own planet. Further, it has also been designated a potentially hazardous asteroid by NASA.

However, an impact is extremely unlikely. According to NASA’s calculations, 7482 (1994 PC1) will pass the Earth on January 18 at a distance of around 1.98 million kilometers away. For context, the Earth’s distance from the moon, approximately 384,000 kilometers, is over five times less than that.

This is in line with NASA’s prior predictions, which estimated that the Earth would be free of risk from any asteroid impacts within the next 100 years.

But had the Earth not been so lucky, the results could have been catastrophic.

‘Hazardous’ asteroid to enter Earth’s orbit next week

RT – December 3, 2021

A large asteroid, listed by NASA as “potentially hazardous,” is going to fly by Earth next week, the agency warns.

Asteroid 4660 Nereus is expected to enter Earth’s orbit on December 11, coming closer to our planet than ever before.

But there is no reason for panic, Boris Shustov, who heads the Institute of Astronomy at the Russian Academy of Sciences, said.

“The asteroid will pass some 4.6 million miles away from Earth, which is about 10 times the distance between the Moon and Earth, so there’s no risk to talk about,” Shustov told RIA Novosti.

What makes it special isn’t its larger-than-usual size (equal to three football pitches), but its unique 1.82-year orbit around the Sun. Nereus approaches Earth at a safe distance roughly every 10 years because of this.

According to the scientists, the asteroid’s regular passing makes it a perfect candidate for a future robotic mission, and even a mining operation – it is believed to be rich in nickel, iron, and cobalt.

Despite currently posing no threat, Nereus is closely monitored by space agencies to make sure it does not deviate from its path.

Bigger Than Burj Khalifa: ‘Potentially Hazardous’ Asteroid to Pass by Earth on Saturday

Sputnik News – August 20, 2021

NASA is keeping a close eye on 1,000 space rocks that are “potentially hazardous” to our planet.

The asteroid known as “2016 AJ193,” classified as “potentially hazardous” by NASA, will whizz past Earth on Saturday, 21 August. The 1.4 km-wide space rock – which is traveling at 94,208 km per hour – will pass within 3,427,445 km of Earth.

The asteroid will approach our planet at 11:10 am ET (8:40 pm IST and 3:10 pm GMT).

NASA will observe the asteroid from 20 to 24 August using radar. It’s 1.5 times the size of the Burj Khalifa, more than three times the size of the Empire State Building, and over 4.5 times the size of the Eiffel Tower – it was spotted in January 2016 by the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) facility, which is part of Hawaii’s Haleakala Observatory.

Every 5.9 years, it orbits the Sun – as it travels towards Earth’s orbit it shoots off in Jupiter’s direction. This visit will be 2016 AJ193’s closest approach to Earth for at least for the next 65 years.

NASA is currently tracking over 26,000 near-Earth asteroids, while over 1,000 are considered potentially hazardous.

An asteroid the size of the Golden Gate Bridge to make “very close encounter” with Earth on first full day of spring

Sophie Lewis – March 12, 2021

An asteroid similar in size to the Golden Gate Bridge will whip past Earth later this month — the largest and fastest asteroid to pass close to our planet this year.

But don’t worry, it won’t get too close.

The asteroid, officially known by NASA as 231937 (2001 FO32), is about 1,300 to 2,230 feet wide, according to observations made by the NEOWISE team, putting it at the smaller end of the scale. It has an orbit period of 810 days.

The asteroid is smaller than the last notable one to make a close approach to Earth, but it will be three times closer, NASA said in a statement Thursday.

2001 FO32 is set to come within 1.25 million miles of Earth at 11:02 a.m. ET on March 21, just one day after the spring equinox. That’s close enough for NASA to classify it as “potentially hazardous” in its database of near-Earth asteroids, a designation given when they come within about 4.65 million miles of Earth, and are larger than 500 feet in diameter.

It will zoom past at almost 77,000 miles per hour, or 21 miles per second — peaking scientists’ interests as one of the fastest space rocks known to fly past Earth. The asteroid is “unusually speedy” due to its highly inclined and elongated orbit around the sun, which takes it closer to the sun than Mercury and twice as far from the sun as Mars.

Apophis asteroid will be visible from Earth this weekend

–

ST. LOUIS – An asteroid the size of three football fields will pass by a star and be visible from Earth on Sunday, February 21. But have no fear, there is no danger of it hitting our planet.

“The more that we can understand the orbits of asteroids like Apophis the better we can prepare,” said Will Snyder, Manager at the St. Louis Science Center McDonnell Planetarium.

According to experts, the 1,000-foot wide asteroid will sweep across the United States around 11:50 p.m. But in order to see this rare event, you have to be located exactly along its path. You can find that path here.

“At home scientists and citizen astronomers will have the opportunity to observe this near-Earth asteroid from their telescope,” said Snyder.

Apophis was first discovered in 2004 and scientists say it’s expected to pass earth and visible to the naked eye with upcoming flybys in 2029, 2036, and 2068.

Rocky start: 2021 will begin with unwelcome, 220-meter wide asteroid visitor, NASA warns

RT – January 1, 2021

As nations across the globe say ‘good riddance’ to 2020, NASA has warned that a monstrous 220-meter asteroid is headed Earth’s way early in the new year.

Before that, this year’s final asteroid, 2020 YB4, measuring just 36 meters in diameter or roughly half the wingspan of a 747, passed by the Earth shortly after 6am UTC at a distance of 6.1 million kilometers. That means, in terms of the threat posed by space rocks at least, the planet made it out of 2020 somewhat intact.

However, in the first days of January, three additional, small Near Earth Objects (NEOs) will grace the Earth with their presence, for a brief time.

Just two days into 2021, the 15-meter asteroid 2019 YB4 will fly by at a safe distance of 6.4 million kilometers. The very next day, it will be followed up by two more chunks of cosmic debris in the form of the 15-meter 2020 YA1 and the 21-meter 2020 YP4, which will pass by at 1.5 and 2.1 million kilometers respectively.

But the biggie will come on January 3, as the relatively mountainous 2003 AF23, measuring an impressive 220m in diameter or about as wide as the Golden Gate Bridge is tall, will shoot past at 6.9 million kilometers.

Mamma Mia! NASA Tracking Asteroid Nearly Double the Diameter of Roman Colosseum Approaching Earth

Sputnik News – August 31, 2020

The so-called ‘Near-Earth Object’, classified as such by the US National Aeronautics and Space Administration (NASA), was first discovered by astronomers in 2010, and is set to cross Earth’s orbit on Sunday.

NASA is tracking a massive, 270 metre-wide asteroid that’s nearly double the diameter of the Great Roman Colosseum, and almost twice the height of Egypt’s iconic Pyramid of Giza.

The asteroid, formally known as object ‘465824 (2010 FR)’, is making its way toward Earth’s orbit at an incredible speed of approximately 50,530 km per hour (or 14 km per second), or over 1.5 times faster than what scientists call high-hypersonic speed.

The object, known as an ‘Apollo’ asteroid because it crosses Earth’s orbit, is not believed to be a threat to life on the planet, according to astronomers from NASA’s Center for Near-Earth Object Studies.

Nevertheless, scientists are monitoring space rocks such as 465824 (2010 FR) due to the effects of the gravitational pull of the planets of our solar system, as well as the Sun, which can alter their trajectory.

The asteroid is expected to hit Earth’s orbit on September 6, and will be just one of about ten near-Earth orbit flybys next month. Two such asteroids – 2020 QG5 and 2011 ES4, will arrive on Tuesday. Two more, 2020 PG6 and 465824 (2010 FR) will arrive on September 2 and 6, respectively. NASA expects ten more asteroid flybys in October.

Russia’s space agency Roscosmos commented on 2011 ES4’s approach on Sunday, promising that the planet “won’t die” from the 25 meter diameter space rock as it zips by the planet at a distance closer to Earth than our Moon. According to Roscosmos’s figures, about 80 similar asteroids approached Earth in August.

Astronomers don’t manage to spot every single asteroid that approaches Earth ahead of time. Earlier this month, a 3 by 6 meter asteroid zipped past Earth just 2,950 km above the Indian Ocean.

Scientists Have Warned That A 400 Foot Tsunami Could Hit The East Coast If An Asteroid Hit The Atlantic Ocean

– August 4, 2020

We live at a time when giant space rocks are whizzing past our planet with alarming regularity.  Sometimes we know in advance that they are coming, and sometimes we don’t.  In fact, on July 28th an asteroid the size of a car zipped past our planet “at a range that rivals the orbits of some high-flying satellites”, but we had only spotted it for the very first time on July 26th.  If we couldn’t see that one until it was nearly upon us, could it be possible that there are much larger potential threats hurtling toward our planet that we currently know nothing about?

In 1998, a big Hollywood movie entitled “Deep Impact” imagined what would happen if a very large asteroid hit the Atlantic Ocean.  It is hard to believe that it has been more than 20 years since it first came out, because I can still remember it very vividly.  In one of the most memorable scenes in the film, a massive tsunami that is hundreds of feet tall slams into the east coast of the United States causing immense death and destruction.

But that is just a movie.  Could something similar actually happen in real life?

On Tuesday, a British news source reminded us that scientists have discovered that such a scenario is actually a very real possibility…

A computer simulation of an asteroid impact tsunami developed by scientists at the University of California, Santa Cruz (USCS), showed waves as high as 400 feet sweeping onto the Atlantic Coast of the US.

Steven Ward, a researcher at the Institute of Geophysics and Planetary Physics at UCSC, and Erik Asphaug, an associate professor of Earth sciences, reported their findings in the Geophysical Journal International.

Of course an asteroid could potentially hit anywhere on the planet, but in their research Ward and Asphaug specifically focused on the Atlantic Ocean, and what their computer simulation came up with was extremely disconcerting…

For the simulation, the researchers chose an impact site consistent with the orientation of the Earth at the time of the predicted encounter – in the Atlantic Ocean about 360 miles from the US coast.

Dr Ward explained that the 60,000-megaton blast of the impact could vaporise the asteroid and blow a cavity in the ocean 11 miles across and all the way down to the seafloor, which is about three miles deep at that point.

Such an impact would send a series of giant waves in all directions, including toward the east coast of the United States.

Experts Say Near Earth Asteroid Due To Come Within 300 Miles Of Earth In November Not A Concern Yet

Charlie Forbes – July 21, 2020

CBS Detroit – There’s a video on Youtube saying we are about to have another “very-close encounter” with an asteroid. What the Jet Propulsion Lab in California calls “Near-Earth-Objects” or NEOs. Now keep in mind asteroids have been coming close or have hit our planet for millions of years, and many do daily. The bulk of asteroids and debris in space as you may remember from science class get burned up in the atmosphere, caused by the friction from the air as objects hit the atmosphere going many thousands of miles per hour.

However, one Youtube video says an asteroid called “2018 VP1“, which is about 6 feet diameter will pass within about 300 miles of our planet on November 2, 2020. However, some experts are saying this nothing to fear. First off there’s the math, asteroid “2018 VP1” is projected to come 0.02 times the distance between the earth and the moon. Given that the moon is 239,000 miles away, 0.02 equates to 4,780 miles. Now your thinking that’s far off right? What’s the big deal? Well, when they compute this stuff through orbital mechanics, they use the center of the celestial body, in this case, the earth. The earth is 7,917 miles across, and half that is 3,958 miles. That is where the video correctly gets its 300-mile estimate from, or a drive from Metro Detroit to Sault Sainte Marie in the UP to put it in perspective.

In a recent article to Mlive, astronomer Mike Murray says while this is very close, it is not as bad as it seems. JPL assigns a confidence number or condition code to NEO’s from 0 to 9. “0” being a very “duck and cover” confident and 9 being very uncertain. Asteroid “2018 VP1” scores a 7 which means the projected forecast is uncertain. Part of that is because in 2018 they observed this for 21 days and only formed an orbital arc for 13 days. Murray says that even if this rock were hit to hit a bullseye on earth, it is only 6 feet across. It would have to be 20 times larger to do damage to a city.

On February 15, 2013 the Chelyabinsk meteor entered the earth’s atmosphere over Russia over the southern Ural region. This asteroid was 11 times larger than “2018 VP1” at 66 feet across and was shared on social media everywhere as it appeared brighter than the sun and was visible up to 62 miles away. The Chelyabinsk meteor exploded about 97,000 feet in the air with the force of 400-500 kilotons of TNT, or 26-33 times the energy of the “Little Boy” atomic bomb that was dropped on Hiroshima. The atmosphere absorbed most of that blast and people were injured from broken windows from nearby buildings. It ended up exploding in an air burst into many pieces. Astronomer Mike Murray says “2018 VP1” would probably break apart or explode like the Chelyabinsk meteor and most that do impact the earth.

So for now the experts and the video makes the point that for now, we’re safe. As we don’t know all the facts on this asteroid’s orbit, but as “2018 VP1” gets closer, hopefully, astronomers will be able to acquire it to make more measurements and know for certain this asteroid’s orbit.

NASA Keeping Tabs on Stadium-Sized Asteroid Headed Toward Earth

Amy Furr – June 4, 2020

The National Aeronautics and Space Administration (NASA) said Wednesday that it was keeping an eye on several asteroids moving closer to Earth in the next few days.

“According to the agency’s asteroid watch, the largest of the five currently being tracked is 1,100 feet wide, roughly the size of a stadium,” WMBF reported.

However, the massive asteroid, expected to be nearest the Earth on Saturday, was not supposed to be a threat because the closest it was predicted to come was 3.16 million miles away.

“There are three others the size of a plane and one the size of a house also making their way to earth over the next few days,” according to Fox 2 Now.

“Scientists also don’t believe there are any concerns from those asteroids either. The closest one is expected to come within 1,830,000 miles of earth later today,” the article noted.

On its website, NASA posted an Asteroid Watch Widget to track the asteroids and comets that would make relatively close approaches to our planet.

“The Widget displays the next five Earth approaches to within 4.6 million miles (7.5 million kilometers or 19.5 times the distance to the moon); an object larger than about 150 meters that can approach the Earth to within this distance is termed a potentially hazardous object,” the site read.

Although it was unlikely for an asteroid to collide with Earth in the near future, scientists from all over the world gathered at a 2019 conference to discuss how to respond to one big enough to destroy a major city, according to CBS News.

“All we have to do is change its speed a little faster or a little slower so that when it crosses Earth’s orbit, it crosses either in front of us or behind us,” stated Dr. Lori Glaze, who is the director of planetary science at NASA.
