Solar System, technical/Asteroid belt
The asteroid belt is between 2 and 3.2 astronomical units from the Sun.
Vesta[edit | edit source]
- diameter= 530 kilometres
- features= Veneneia basin
Vesta doesn't have enough gravity to form it into a complete sphere, which is why it is not a dwarf planet.
The Dawn spacecraft has visited Vesta as one of its objectives.
Main belt comets[edit | edit source]
These are comets that are within the asteroid belt. Only a handful of main belt asteroids have been discovered. It is uncertain what causes these objects to have a trail, but this event only occurs for a few days at a time.
