NASA confirms mysterious object orbiting Earth is 1960s-era rocket booster

The mystery is finally over — the space object that was captured by Earth’s orbit is indeed a rocket booster from the 1960s, NASA confirmed.

On Wednesday, the government space agency said the object known as «2020 SO» is not an asteroid, but rather a part of a Centaur rocket booster from the Surveyor 2 spacecraft, which launched toward the moon in 1966.

“Due to extreme faintness of this object following [Center for Near-Earth Object Studies] prediction it was a challenging object to characterize,” said Vishnu Reddy, an associate professor and planetary scientist at the Lunar and Planetary Laboratory at the University of Arizona, in a statement. “We got color observations with the Large Binocular Telescope or LBT that suggested 2020 SO was not an asteroid.”

“This conclusion was the result of a tremendous team effort,” Reddy added. “We were finally able to solve this mystery because of the great work of Pan-STARRS, Paul Chodas and the team at CNEOS, LBT, [Infrared Telescope Facility], and the observations around the world.”

On Tuesday, the rocket booster made its closest brush with Earth, when it came within 50,000 kilometers (31,000 miles) of the planet, according to Virtual Telescope Project founder Gianluca Masi.

NASA has posted a video of 2020 SO’s looping orbits around the Earth.
