Unknown object to pass by Earth today

A mysterious object is expected to pass by Earth today. Astronomers have named it 2020 SO. They have been tracking the visitor since September when it was spotted from an observation station in Hawaii.

The object is not an asteroid or even a UFO. But NASA scientists believe it’s a piece of space junk leftover from early U.S. space exploration.

“It’s probably the Centaur upper stage rocket booster that helped lift NASA’s ill-fated Surveyor 2 spacecraft toward the Moon in 1966,” NASA officials wrote in a November 12th research update

Computer modeling helped their team trace the likely origin to the 1966 launch.

The object will reach its closest to Earth at 3:50 AM ET on Tuesday. It will be just 31,605 miles away. It measures an estimated 15-33 feet in width.
