Earth is set to capture a minimoon in October - but some experts it could be ...

Astronomers have spotted an object with an incoming trajectory towards Earth that could become a temporary minimoon.

Dubbed 2020 SO, the entity has been on an Earth-like orbit for more than a year and is set to become trapped in our planet's gravity starting in October and stay until May 2021. 

However, some experts have noticed it is moving much slower than a typical asteroid and suggest it could be man-made space junk.

A NASA scientist has speculated that it may be a discarded part of the Surveyor 2 Centaur rocket that launched in 1966.

Tony Dunn, an astronomer, told DailyMail.com: 'Further observations will reveal its density. If it is hollow like a rocket booster, solar radiation pressure will significantly alter its course.'

DailyMail.com has contacted NASA for more information and has yet to receive a response.  

Earth has only had two minimoons on record – one in February 2020 and the other in 2006.

Unlike the other two, 2020 SO has yet to be confirmed as an asteroid, as some scientists believe it could be space junk hurling towards Earth.  

However, 2020 SO has been classified as an Apollo asteroid in NASA's Jet Propulsion Laboratory (JPL) Small-Body Database, which is a class of asteroids whose paths cross Earth's orbit.
