List

This is a list of all the moons of planets and dwarf planets in the Solar System. Those 19 moons that are large enough to have achieved hydrostatic equilibrium are listed in bold. The seven largest moons are listed in bold and italic. Sidereal period differs from semi-major axis because it depends on the mass of the primary as well as the satellite's distance from it.

Famous quotes containing the word list:

    “Modern tourist guides have helped raised tourist expectations. And they have provided the natives—from Kaiser Wilhelm down to the villagers of Chichacestenango—with a detailed and itemized list of what is expected of them and when. These are the up-to- date scripts for actors on the tourists’ stage.”
    —Daniel J. Boorstin (b. 1914)

    “Feminism is an entire world view or gestalt, not just a laundry list of women’s issues.”
    —Charlotte Bunch (b. 1944)

    “Hey, you dress up our town very nicely. You don’t look out the Chamber of Commerce is going to list you in their publicity with the local attractions.”
    —Robert M. Fresco, and Jack Arnold. Dr. Matt Hastings (John Agar)
