Vesta revolves around the Sun once in 3.63 years in a nearly circular moderately inclined (7.1°) orbit at a mean distance of 2.36 astronomical units (AU; about 353 million km [219 million miles]).
Why is Ceres a dwarf planet?
Dwarf planet Ceres is the largest object in the asteroid belt between Mars and Jupiter and the only dwarf planet located in the inner solar system. Called an asteroid for many years, Ceres is so much bigger and so different from its rocky neighbors that scientists classified it as a dwarf planet in 2006.
