TORONTO -- A small asteroid that scientists project could orbit Earth until next spring might actually just be 鈥渟pace junk鈥� more than half a century old.
The new object spotted by astronomers last week and dubbed , a provisional designation based on the discovery date, is expected to fall into our orbit, where it will spin from mid-October to May 2021.
If it doesn鈥檛 change course, it could be the third object -- sometimes referred to as "minimoons" -- confirmed by scientists to be captured in Earth鈥檚 celestial path, according to news site . In 2006, asteroid orbited with Earth for about nine months, and in 2020, scientists realized that a rock called had been orbiting for three years already.
Though it is still unclear whether 2020 SO is a small asteroid or a man-made object, one NASA scientist with the Jet Propulsion Laboratory in Southern California has 鈥渢entatively identified鈥� it as a piece from the failed Surveyor 2 moon lander program in 1966. At the time, NASA used 鈥渕ulti-stage鈥� rockets, some parts of which would fall back to the ground while others would be discarded in space.
According to a member of the The Minor Planet Mailing List, an online group of space enthusiasts and lunar researchers, the velocity projections of the object suggest 鈥渋t is unlikely it is a natural body鈥� and that is is 鈥�.鈥�
Current estimates put the size of the object between roughly six and 14 metres in length, which is consistent with the size of the 1966 rocket piece NASA identified, according to ScienceAlert.
It won鈥檛 get very close and is on a 鈥�,鈥� wrote orbit simulator Tony Dunn on Twitter. In fact, projections suggest it will pass by Earth on Dec. 1 at a distance of about 50,000 kilometres, and later in February at about 220,000 kilometres.
