The Solar System's Major Moons
The Solar System contains 18 or 19 natural satellites of planets that are large enough for self-gravity to make them round. (Why the uncertain number? Neptune’s moon Proteus is on the edge.) 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.”

Son los primeros, no una selección, y si te ha picado la curiosidad visita su página y verás como estás de acuerdo con una de estas dos frases hechas:
"hay gente que se aburre un montón"
o
"la necesidad agudiza el ingenio"
Yo me quedo al 50% de ambas.
