Homeworld

The designation homeworld refers to the planet where a certain species originates from. For example, Earth is the homeworld of the Human species and Qo'noS is the homeworld of the Klingon species.

In some cases more than one intelligent species originates from the same planet. Examples of this are Trill and Xindus.

In order for a planet to be a homeworld, it does not have to be the site where a species evolved, but where the cultural and social origin of the certain species lies, just as is the case with the Romulans, who evolved on the planet Vulcan but moved to their current homeworld Romulus almost 2,000 years ago.
