2001 FO32: Big asteroid sweeps closest this weekend

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.

Say goodbye to Earth’s mini-moon on February 1 and 2

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!
