It’s flying nearer than the moon and could resemble a building in size
An unusually big asteroid will pass by Earth especially near on Monday night, and the encounter will be streamed live online. No need to panic as the flyby will be entirely secure and doesn’t pose any jeopardy to anything or anyone on Earth or any of our satellites. However, asteroid 2021 EQ3 will come nearer to Earth than our sole natural satellite.
Sky surveys and other telescopes find a space rock moving closer than the moon every few days, on average. Most of these asteroids are only a few meters beyond, possibly making them no larger than a bus.
But, Asteroid 2021 EQ3 could have a diameter of up to 125 feet (38 meters), making it resemble the size of a small apartment building. That’s also approximately the same size as the meteoroid that banged into the atmosphere above Russia in 2013, producing a shock wave that blew out thousands of windows in the city of Chelyabinsk below, wounding hundreds.
2021 EQ3 will pass closest above us at approximately 9:45 p.m. PT Monday, at a distance of almost 173,000 miles (278,000 kilometres), which is 72% of the distance from the Earth to the moon.
This makes 2021 EQ3 the second-largest object to come nearer than the moon in 2021.
It’s also distinctive from 2001 FO32, which is an ideal monster with a diameter of almost a mile. That asteroid is set to pass by on March 21 but at a distance five times distant away from the moon.
The asteroid’s size also makes it a genuine object to follow, and the Virtual Telescope Project based in Rome will be streaming an online watch party through its website.
