‘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.

Several asteroids larger than the Great Pyramid of Giza will fly by Earth in coming weeks

ETH – October 14, 2021

Several asteroids bigger than the Great Pyramid of Giza will closely pass by Earth in the upcoming weeks, including one this week. According to data from NASA’s Center for Near-Earth Object Studies, the asteroid 2021 SM3, which was discovered just last month, will pass by our planet on Friday.

The diameter of the asteroid is up to 525 feet, just bigger than the 482-foot long Great Pyramid of Giza. An object of that size would be enough to “cause local damage to the impact area” if it were to hit Earth.

2021 SM3 is classified as a near-Earth object, which NASA says “are comets and asteroids that have been nudged by the gravitational attraction of nearby planets into orbits that allow them to enter the Earth’s neighborhood.” The bodies are anything that comes within 120 million miles of Earth.

At its closest point, the asteroid will be about 3.6 million miles from Earth. Though that sounds like a safe distance, it’s much closer than our neighbor Venus, which can be 74.8 million miles away depending on each planet’s orbit. 2021 SM3 won’t be the only large asteroid that passes by Earth soon.

Seven asteroids bigger than SM3 will come close to our planet by the end of November. Of all the recently approaching asteroids, 1996 VB3 will be the closest to Earth at 2.1 million miles on Oct. 20. That asteroid has a diameter of up to 754 feet.

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.

Solar cycle 25: the Sun wakes up

Space Daily – October 30, 2020

The Sun has entered its 25th solar cycle and is about to wake up. For the last few years our star has been pretty sleepy, with few sunspots, bright flares or massive ejections of magnetized plasma emanating from its surface. This quiet period is known as the solar minimum, but things are starting to heat up again.

Experts on the Solar Cycle 25 Prediction Panel recently announced that the Sun has officially entered a new cycle, its 25th since we’ve had enough data to reliably recognize them. While we can expect space weather to get more exciting in the next few years, with peak sunspot activity expected in 2025, the panel came to the consensus that this next cycle will be very similar to the previous, both generally weaker than the average solar cycle.

“While small and medium-sized solar storms are more likely during peak solar activity,” explains Juha-Pekka Luntama, Head of ESA’s Space Weather Office, “it is important to remember that individual large solar events, huge flares and coronal mass ejections, can happen at any point, independent of where we are in the solar cycle or how strong the cycle becomes.”

If such solar storms impact Earth, they can create geomagnetic storms in our magnetosphere. While good news for aurora hunters, these storms can disrupt and even damage power grids on Earth and satellites in orbit, and the vital services they provide.

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.

‘Ring of Fire’ annular solar eclipse to grace the skies soon after the solstice

–

An annular solar eclipse will take place on Sunday, June 21, 2020. This is one of the most breathtaking celestial events when the Moon partially obscures the Sun, allowing a “ring of fire” on its edges. The eclipse will start several hours after the solstice.

The annular solar eclipse occurs when the Moon is farthest away from the Earth in its orbit, thus, appearing smaller in our skies, relative to the Sun.

The difference in apparent size is what sets annular eclipses apart from full eclipses– when the nearer position of the Moon (with its average radius of  800 km or 1 000 miles) makes it look the same size as our star (with a radius of around 696 000 km or 432 000 miles).

A stunning example of this was taken by photographer Colin Legg and astronomy student Geoff Sims in Western Australia in May 2013. The ring of fire is seen being distorted by the Earth’s atmosphere.

A complete ring of fire will be visible from central Africa through Asia, while many other areas, from southern Europe to the northern portions of Australia, will see a partial annular eclipse.

The instant of greatest eclipse takes place at 06:40 UTC, with the Sun in the constellation Taurus. This is 6.2 days after the Moon reaches apogee.

The synodic month in which the eclipse takes place has a Brown Lunation Number of 1206, NASA’s Fred Espenak aka Mr. Eclipse noted. The eclipse belongs to Saros 137 and is number 36 of 70 eclipses in the series. All eclipses in this series occur at the Moon’s ascending node. The Moon moves southward with respect to the node with each succeeding eclipse in the series and gamma decreases.

At the peak of the eclipse, the Moon will obscure 99.4 percent of the Sun as the pair puts a spectacular display across the skies of northern India.

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.

‘Potentially Hazardous’ Asteroid the Size of Golden Gate Bridge Approaching Earth at 11 km/s

Sputnik News – May 11, 2020

Several space rocks are expected to cross paths with earth this month, but the largest one, and potentially the most dangerous, is the Apollo-class 1997 BQ asteroid, as researchers believe that any space objects measuring close to one kilometre in diameter could have devastating consequences for our planet.

NASA disclosed that 1997 BQ asteroid, also known as 136795, will “closely approach” Earth on the evening of 21 May, sweeping round at a speed of around 11.6 kilometre per second. The space rock was first observed back in January 1997 and is measured at between 0.668 and 1.493 kilometers in diameter, judging by its brightness, which makes it “roughly” comparable in size to the Golden Gate Bridge, the space agency notes.

The asteroid is deemed “potentially hazardous” by NASA, as it belongs to the Apollo category of space rocks, the trajectory of which crosses the orbit of our planet. It might be too early to sound an alarm though, as 1997 BQ will only approach our home from a distance of 0.04115 astronomical units, or 6.156 million kilometres in human terms.

However, NASA’s Centre for Near Earth Object Studies is closely monitoring the object which is considered to be larger than 97% of other space asteroids. Any rocks that are close to one kilometre in size can be potentially dangerous to our planet, the National Near-Earth Object Preparedness Strategy revealed in 2018, as they can create a significant regional impact with secondary effects such as tsunamis, without even making contact with the earth.

NASA Missed an Asteroid that Came Closer to Earth than the Moon

Adam Eliyahu Berkowitz– April 16, 2020

An asteroid the size of a house was discovered by NASA last week, which was just in time to announce its near-miss on Wednesday night. Asteroid 2020 GH2 is estimated to be 43 to 70 feet wide according to Space.com.

NASA’s Planetary Defense Coordination Office assured Earth-dwellers that our planet was safe from destruction, tweeting a video that attempted to put a near-earth pass into perspective.

The video depicted the Earth as a basketball, the moon as a tennis ball 25 feet away, and the asteroid responsible for the demise of the dinosaurs as a grain of salt “a couple of blocks away.” But GH2 was not a couple of blocks away. GH2 passed by the Earth at a distance of 220,000 miles, which put it about 16,000 miles closer than the moon.

Largest Planet-Killer Asteroid To Approach Earth This Month Arriving On Saturday

– February 12, 2020

A potentially hazardous asteroid that’s big enough to trigger a nuclear winter and mass extinction events on Earth following a collision will intersect the planet’s path this weekend. According to the data collected by NASA, the approaching asteroid is larger than the tallest man-made structure in the world.

NASA’s Center for Near-Earth Object Studies (CNEOS) has identified the incoming asteroid as 163373 (2002 PZ39). As indicated in CNEOS’ database, this asteroid is currently traveling toward Earth at a speed of almost 34,000 miles per hour.

CNEOS estimated that 163373 (2002 PZ39) has a diameter of around 3,250 feet, making it significantly bigger than the Burj Dubai, which is currently the tallest building in the world. Given its incredible size, 163373 (2002 PZ39) will be the biggest asteroid to approach Earth this month.

According to CNEOS, 163373 (2002 PZ39) is an Apollo asteroid, which means it is known to intersect Earth’s path around the Sun from time to time. Due to its dangerous orbit and massive size, approaching space rock has been labeled as a potentially hazardous asteroid.

“Potentially Hazardous Asteroids (PHAs) are currently defined based on parameters that measure the asteroid’s potential to make threatening close approaches to the Earth,” NASA explained in a statement.

Since 163373 (2002 PZ39) follows an Earth-crossing orbit, it has a chance of colliding with Earth every time it passes the planet. If the asteroid collides with Earth, it will cause a major impact event.

NASA and other space agencies have warned that kilometer-sized asteroids can do a lot of damage to Earth. If 163373 (2002 PZ39) hits the planet, its initial blast would instantly kill off millions.

Then, due to its size, the energy from its explosion would be enough to trigger a global nuclear winter that could last for years. The harsh environmental changes triggered by the asteroid’s impact could lead to the mass extinction of different species.
