Homeworld

A homeworld is the origin of a species, if they come from a planet.

In most cases, the species is named after the planet they originate from. A few examples:
 * Gorn are from Gornar
 * Tholians are from Tholia
 * Kzinti are from Kzin
 * Andorians are from Andoria
 * Vulcans are from Vulcan

In some cases, the species name is completely different to their planet's name:
 * Klingons are from Qo'noS

Some species' names are in a different language to that spoken widely by the planet's population. One example is Earth: the Latin name for Earth is Terra, and the "second" name for Humans (not used as much, except in the mirror universe), is "Terrans".
