Moons of the Solar System Postcards

Everybody knows by name the 8 planets of the Solar System (and Pluto).

But what about the 181 moons?

This is a minimally illustrated postcard set made of 9 cards containing every moon and dwarf planet pictured with its planet in proportion.

Ganymede is the biggest moon of the Solar system, bigger than Mercury.


Phobos could fit inside Olympus Mons, the tallest known mountain of the Solar system.
Our moon is the biggest relative to its planet. The size of moons and planets inside a card are in proportion.
There are currently 5 recognized dwarf planets, but the number could grow up to hundreds. Ceres is the only one in the asteroid belt (between Mars and Jupiter), the others are trans neptunian.
