Questions tagged [planets]

Planets are large celestial bodies in orbit around a star. Sometimes, large moons are also called planets - especially if they are able to support some kind of life. A typically habitable planet is about 6,000 kilometres in diameter, while large gas giants can be much bigger. Planets can be host to millions of sentient inhabitants, or barren wastelands, or anywhere in between.
