According to the American “Space” website, NASA researchers learned last December that the object is not a space rock at all, but rather the remnants of a boosted missile in the 1960s that participated in the US Moon missions Surveyor.
This small moon took its closest approach to Earth on December 1, a day before NASA identified it as a long-lost support, but it returns in another cycle, where it will finally approach Earth next Tuesday, February 2, at 140,000 miles. (220,000 km) from Earth, or 58% of the road between the Earth and the Moon.
The booster will then drift away, leaving Earth’s entire orbit by March 2021, according to EarthSky, and after that, it will be just another object orbiting the sun.
The virtual telescope project in Rome will host an online goodbye to the object on the night of February 1.
NASA has learned that the object has approached Earth several times over decades, even getting relatively close in 1966, the year the agency launched its lunar probe Surveyor 2 on the back of the enhanced Centaur rocket.
This gave scientists the first significant evidence that 2020 SO was manmade; They confirmed this after comparing the chemical composition of the object with another compound of the missile, which has been in orbit since 1971.
