Celestia includes several catalogs of Locations on the Earth and on objects elsewhere in the Solar System. They're short, only containing lists of major features, like the Earth's oceans, continents and capital cities of nations. More extensive catalogs of Locations are available as Addons.

Locations are labeled positions, usually on the surfaces of objects defined in SSC catalog files. They're shown if you select the option "Label Features" in the menu Render / Locations...

When Locations are enabled, you can use Celestia's goto functions to travel to them.
