An asteroid the size of a football stadium isn’t hitting Earth, but it’ll come closer than ever: Watch live tonight

An asteroid the “size of a football stadium” is moving at a fast pace toward Earth and will be visible via livestream in the early morning hours of Wednesday, December 4, when it makes its closest approach ever to our planet—1.37 million miles away.

Asteroids are chunks of rock remaining from the formation of our solar system. This massive space rock, known as 2020 XR, is traveling at about 27,500 miles per hour and will bypass Earth at 12:27 a.m. EST on Wednesday, according to NASA’s Jet Propulsion Laboratory.

To put it in perspective, asteroid XR is about 1,200 feet in diameter, large enough to wipe out a small city. It’s designated as a “near earth object,” or NEO, based on its size and how close it orbits to the sun. NEOs are “potentially hazardous”—but rest assured, this one isn’t.

How can I see the asteroid live?

The Virtual Telescope Project (VTP) is providing a free livestream starting at 1:30 p.m. EST on Tuesday, December 3 leading up to the event. The asteroid will also be visible through an 8-inch telescope, according to the European Space Agency (ESA).

When will it appear again?

2020 XR is expected to bypass Earth again in about four years, but it won’t approach this close again until at least 2196, when it will be an estimated 11.3 million miles away.
