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!
Deborah Byrd created the EarthSky radio series in 1991 and founded EarthSky.org in 1994. Today, she serves as Editor-in-Chief of this website. She has won a galaxy of awards from the broadcasting and science communities, including having an asteroid named 3505 Byrd in her honor. A science communicator and educator since 1976, Byrd believes in science as a force for good in the world and a vital tool for the 21st century. "Being an EarthSky editor is like hosting a big global party for cool nature-lovers," she says.
