The object, dubbed 2020 SO by astronomers, will come within "just" 31,605 miles of our planet at 3:50 a.m. ET on December 1, according to NASA's Center for Near Earth Object Studies (CNEOS.) This is an "extremely close," albeit safe, approach... The object, which is estimated to measure between 15-33 feet across, was discovered by the Pan-STARRS survey based in Maui, Hawaii, on September 17, 2020. This find was confirmed two days later by the Minor Planet Center, which is responsible for the designation of minor bodies in the solar system. Initial observations suggested that the object was an asteroid....

A mysterious object temporarily orbiting Earth is a 54-year-old rocket, not an asteroid after all, astronomers confirmed Wednesday. Observations by a telescope in Hawaii clinched its identity, according to NASA's Jet Propulsion Laboratory in Pasadena, California. The object was classified as an asteroid after its discovery in September. But NASA’s top asteroid expert, Paul Chodas, quickly suspected it was the Centaur upper rocket stage from Surveyor 2, a failed 1966 moon-landing mission. Size estimates had put it in the range of the old Centaur, which was about 32 feet (10 meters) long and 10 feet (3 meters) in diameter. Chodas...

...the item is now believed to be a rocket booster from NASA’s Surveyor 2 mission which crash landed on the Moon in 1966... Of course, there’s still a chance that 2020 SO is actually an asteroid, in which case it would be considered a minimoon while in direct orbit around the Earth. However, an old rocket booster finding would merely be considered ‘space junk’ and join the 57,000-plus pieces of human debris currently being tracked by various entities. One astronomer’s space ‘trash’ is a vintage space collector’s treasure? You decide. You can watch more on NASA’s Surveyor missions below:...

Astronomers first noticed the object now known as 2020 SO last September. Orbit models quickly showed that both the low speed and trajectory of the approaching object were unusual. The models showed that Earth would capture this object – temporarily – as a new mini-moon. And that’s what happened. 2020 SO has been orbiting Earth since November 8. Following further analysis of its motion – and a very close approach of the object (just 30,000 miles, 50,000 km or 0.13 lunar-distances) on December 1 – NASA was able to confirm that the object is a relic of the early Space...

Instead of a cosmic rock, the newly discovered object appears to be an old rocket from a failed moon-landing mission 54 years ago that's finally making its way back home, according to NASA's leading asteroid expert. Observations should help nail its identity. 2020 SO, as it is formally known, is actually the Centaur upper rocket stage that successfully propelled NASA's Surveyor 2 lander to the moon in 1966 before it was discarded. The lander ended up crashing into the moon after one of its thrusters failed to ignite on the way there. The rocket, meanwhile, swept past the moon and...

A strange space object approaching Earth is about to get captured by our gravity and become a new, temporary “mini-moon.” The object, which is dubbed 2020 SO, could be an asteroid. Or it could be part of the Surveyor 2, a robotic spacecraft launched to the moon on Sept. 20, 1966, according to the science and nature website EarthSky.org Traveling at the extremely-slow-for-space speed of 1,880 miles per hour, the object was seen last week by astronomers in Hawaii, and it’s on course to be captured by Earth from October 2020 until around May 2021, according to EarthSky. Astronomers here...
