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).
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.
Using the installed catalogues, the names of celestial objects can be displayed, including artificial satellites. The names and locations of Earth features such as continents, mountains, seas, oceans, and cities can also be displayed. Surface features on other celestial objects such as craters, basins and canyons can be shown as well.

In general these orbits are not circular. When farthest from the Moon (at apoapsis) a spacecraft is said to be at apolune, apocynthion, or aposelene.
