Planets

I'm currently in the process of cleaning up this category. A lot of these articles are double categorized, which really isn't necessary as most of them fit into one of the three sub-categories.--Spartacus ^{Talk • Contribs} 12:21, 2 June 2015 (EDT)

Isn't the category used to categorize worlds that are planets? If the planet just happens to be a human colony, then the "human colonies" category is added in addition to the planet one. - NightHammer (talk) 13:38, 2 June 2015 (EDT)
