Apophis' flyby in early March 2021 enabled astronomers to conclude there's no chance this asteroid will strike Earth anytime soon. "A 2068 impact is not in the realm of possibility anymore," one scientist said, "and our calculations don't show any impact risk for at least the next 100 years."
When the asteroid labeled 2001 FO32 sweeps closest to Earth on March 21, 2021, it'll be moving at such a fast pace that observers using telescopes might be able to detect its motion - its drift in front of the stars - in real time. Charts and info here.
In November, a new mini-moon began orbiting Earth. NASA later confirmed it's a lost-and-found 60s-era rocket from the Surveyor 2 moon mission, launched more than 50 years ago. Now the object - SO 2020 - is coming close again for one last time. Here's how to see it!
Asteroid 2000 WO107 passed Earth safely on November 29, at 11 times the moon's distance. Astronomers at Goldstone bounced radar signals from its surface and discovered it's 2 asteroids that touched, and stuck.
Discovered last June, Comet C/2020 M3 (Atlas) is closest to Earth - millions of miles away - on Saturday, November 14, 2020. It's in an easy-to-find location, if you have a dark sky. Charts and photos here.
Watch online today as asteroid 2020 SW swoops in for its closest approach to Earth on Thursday. The asteroid will pass just 7% of the moon's distance. Charts here for telescope users. How to watch online.
