No Belt Can Contain This Asteroid!Listen 7:15
There’s the asteroid belt that we all know between Mars and Jupiter; there’s the Kuiper Belt out beyond Neptune, the most famous inhabitant of which is Pluto; but did you know about the asteroid that orbits the Sun inside the orbit of Venus?
2020 AV2 is one of a group of 21 asteroids that orbit inside Earth’s orbit – that is between the Earth and the Sun and 2020 AV2 orbits inside Venus’ orbit, the only one discovered so far to do so. The whole group is called Atiras or IEO’s – interior earth objects. 2020 AV2 takes 151 days to orbit the Sun. Eventually, it’ll crash into Venus or Mercury (but not Earth).
