Following this pattern, several hypothetical bodies were given names: Vulcan for a planet within the orbit of Mercury; Phaeton for a planet between Mars and Jupiter that was believed to be the precursor of the asteroids; Themis for a moon of Saturn; and Persephone, and several other names, for a trans-Plutonian planet.
Every human language has its own word for the Earth's Moon, and these words are the ones normally used in astronomical contexts.However, a number of fanciful or mythological names for the Moon have been used in the context of astronomy (an even larger number of lunar epithets have been used in non-astronomical contexts).
Size (left) and distance (right) of a few well-known galaxies put to scale. The following is a list of notable galaxies.. There are about 51 galaxies in the Local Group (see list of nearest galaxies for a complete list), on the order of 100,000 in the Local Supercluster, and an estimated 100 billion in all of the observable universe.
If the members of the task group agree that the name is appropriate, it can be retained for use when there is a request from a member of the scientific community for a name of a specific feature. Names that pass review by a task group are submitted to the IAU Working Group for Planetary System Nomenclature (WGPSN).
Two of the new moons orbit in the same direction as the planet rotates, which requires a name that ends in -a; the other three travel in the opposite direction and will be given names that end in ...

The full moon has a different name depending on when it occurs each month, since Native Americans marked their calendars by the moons. How the 'supermoon' got its name -- along with 27 other weird ...
This shape is referred to as a phase because it gradually changes in a regular cycle over the course of a synodic month: as the orbital positions of the Moon around Earth and Earth around the Sun change, the visibility of the side of the Moon that constantly faces Earth alternates between completely illuminated (known as a full moon) and ...
