The largest asteroid flyby of the year is almost here: How to watch – CNET

2021 EQ3 will pass closest above us at roughly 9:45 p.m. PT Monday night, at a distance of around 173,000 miles (278,000 kilometers) — that’s 72% of the distance from the Earth to the moon.

Asteroid 2021 EQ3, however, could have a diameter of up to 125 feet (38 meters), making it more like the size of a small apartment building. That’s also about the same size as the meteoroid that slammed into the atmosphere above Russia in 2013, creating a shock wave that blew out thousands of windows in the city of Chelyabinsk below, injuring hundreds.

You may have seen headlines about an #asteroid that will safely fly by Earth on March 21. While this asteroid, known as 2001 FO32, is large, it will safely zip past Earth at a distance of 1.3 million miles—five times further away than the Moon—and poses no risk of hitting Earth.
Sky surveys and other telescopes spot a space rock passing closer than the moon every few days, on average. Most of these asteroids are just a few meters across, likely making them no larger than a bus.

This makes 2021 EQ3 the second largest object to come closer than the moon in 2021.
The asteroid’s size also makes it a good object to track, and the Virtual Telescope Project based in Rome will be streaming an online watch party via its website.
