Earth is getting a small new moon, however it may need been made by individuals.

Astronomers on the Catalina Sky Survey in Arizona first detected the article again in February as a flash of sunshine darting throughout house.

Proper this second, it isn’t in orbit across the Earth, however it’s close by. And it will enter Earth’s orbit for some time in 2020 earlier than heading out to circle the solar once more.

The preliminary assumption was that this mysterious blip was an asteroid. The article, termed 2020 SO2 by the Jet Propulsion Laboratory, seems to have been briefly captured by Earth’s gravity. Earth has captured “minimoons” like this earlier than, and scientists have noticed them a pair instances in recent times. It is a pure a part of our planet’s motion by house.

However some observers now say this minimoon won’t be pure in any case. Individuals constructed it, they assume, again within the Sixties.

There’s been some disagreement on this level, which performed out on an astronomy message board often known as the Minor Planet Mailing Record (MPML), a web-based neighborhood frequented by professionals and hobbyists.

The difficulty is that 2020 SO2 is in an orbit across the solar that intently matches Earth’s. Objects like that typically fall into Earth’s gravity and find yourself orbiting for a short time. There are many pure asteroids that behave this manner, and there are even rocket elements that people have  launched into house which have comparable orbits.

By analyzing 2020 SO2’s present actions and extrapolating them backward in time through the use of laptop simulations, observers have labored out that this object would have final orbited Earth in 1966 or 1967. That would imply that 1966 or 1967 is when it was launched into orbit within the first place, or when 2020 SO2 naturally approached Earth.

However distinguishing the 2 potentialities is hard. Initially, Sam Deen, an newbie astronomer in California, posted that no 1966 or 1967 launches match 2020 SO2’s habits, which means that the curious object was seemingly pure. (Deen has been cited by NASA prior to now.) Then Paul Chodas, director of NASA’s Middle for Close to Earth Object Research, advised CNN that it was seemingly a rocket from Surveyor 2, an uncrewed NASA moon mission that launched on September 20, 1966. The article’s orbit is so just like Earth’s, he mentioned, that it most likely got here from Earth. Others on the MPML agree.

One other newbie astronomer, Tony Dunn, created a simulation of the article’s path, which is able to take it very near Earth in December and once more in February.

It is doable that as 2020 SO2 comes nearer, extra detailed observations will  settle the matter. However within the meantime, we’re left questioning whether or not Earth’s incoming minimoon is a long-lost factor from this planet, or an area rock dropping in for a brief go to
