The Solar System's Major Moons.

태양계의 주요한 위성들.


The Solar System contains 18 or 19 natural satellites of planets that are large enough for self-gravity to make them round. They are shown here to scale with each other. Two of them are larger than Mercury; seven are larger than Pluto and Eris. If they were not orbiting planets, many of these worlds would be called “planets,” and scientists who study them are called “planetary scientists.”
