Size comparison: Moon vs Pluto

Size comparison between our satellite the Moon and the dwarf planet Pluto.

Pluto is present in the Kuiper Belt, a circle of bodies that lie beyond the planet Neptune. It is the first and largest of the objects that have been discovered in the Kuiper Belt. In 2015, the New Horizons probe flew over the planet, allowing detailed observation, as well as precise measurements. We were thus able to detect the presence of tholins, organic macromolecules, which can be at the origin of the emergence of life.

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.
