As expected, gigantic Asteroid 231937 2001 FO32, skimmed Earth at a speed of about 21 miles per second (76,980 miles per hour) on Sunday. Not only was it the largest space rock we anticipate seeing up close in 2021, it was also one of the fastest.

Also, as expected (and prayed for), Asteroid 231937 2001 FO32 did not make contact with Earth despite zooming by at just 5.3 lunar distances away from our planet.

Asteroid 231937 2001 FO32, at up to 2,230 feet (680 meters) wide, is larger than 97% of all asteroids recorded by NASA so if it had nicked us, it would have been very, very bad.

The next time Asteroid 231937 2001 FO32 will come this close to Earth won’t be until 2052.

“The reason for the asteroid’s unusually speedy close approach is its highly inclined and elongated (or eccentric) orbit around the sun, an orbit that is tilted 39 degrees to Earth’s orbital plane,” NASA officials said in a statement. “This orbit takes the asteroid closer to the sun than Mercury and twice as far from the sun as Mars.”

Astrophysicist Gianluca Masi of the Virtual Telescope Project in Ceccano, Italy explained the above photo.

The image above comes from a single 120-second exposure, remotely taken with the “Elena” (PlaneWave 17″+Paramount ME+SBIG STL-6303E) robotic unit available at Virtual Telescope. Imaging conditions were extreme: 2001 FO32 was incredibly low on the Eastern horizon (11.0 deg. !), with the target almost completely “eclipsed” by the observatory walls, while the sky was brighter and brighter because of the morning twilight. But we were lucky and we could capture the asteroid in two images: here we share the best one!

At the imaging time, asteroid (231937) 2001 FO32 was at about 2.5 millions of km from the Earth and it was quickly leaving us. It was discovered by the LINEAR on 23 Mar. 2001, exactly 20 years ago.

According to Space.com

Like a rock rolling down a hill, asteroid 2001 FO32 picks up speed as it falls inward toward the sun and then slows as it heads back out toward Mars. The asteroid takes more than two years (810 days to be exact) to complete one orbit and won’t pose an impact risk to the Earth for centuries, despite 2001 FO32’s classification as a “potentially dangerous asteroid,” NASA said.

The Virtual Telescope Project also captured very cool footage of Asteroid 2001 FO32 which, unlike most space rocks that pass by the planet, was so big and so close that observers using 8″ or larger telescopes may have been able to detect its motion in real time.
