Largest asteroids: Ceres
Ceres is the biggest asteroid in the belt between Mars and Jupiter and was the first found in 1801, even thought to be a planet at the time.
In the 1850s, it was categorized as an asteroid, but in 2006, it was reclassified as a dwarf planet.
While it is no longer classified as an asteroid, it claims the top rank with a diameter of 580 miles.
Ceres is named after the Roman goddess of corn and harvests, and the term cereal comes from the same root.
Ceres took 1,682 Earth days, or 4.6 years, to complete one round around the sun.
Every nine hours, it completes one rotation around its axis.
