Ceres vs Moon size comparison

Here is the comparison of the size of the dwarf planet Ceres with our natural satellite, the Moon.

Ceres is the largest object in the main asteroid belt between Mars and Jupiter. Its round shape is explained by the fact that Ceres is wide enough to be rounded by its own gravity. For 50 years, Ceres was considered a planet, before being declassified as an asteroid.

Light points

Cérès presents several luminous points present in a crater 80 km in diameter. It was initially thought that this was due to degassing. Ultimately it would be the reflection of the sun on a large surface of ice and salt. Probably a form of brine containing hydrated magnesium sulfate.

Note: if one of the objects is not visible, it just means that it is too tiny to be displayed compared to the other one.
