Is Starfleet just one planet? I know they have multiple races and alien species in it. But I'm not sure if it's just Earth. Confederation seems much bigger.

i should have said Federation.

In 2373, the United Federation of Planets consisted of at least 150 memberplanets, spread over 8,000 light years. (Star Trek: First Contact)


Presumably the admission policy of the Federation regards governments and/or planets, and not whole species. In practice, a planet had to be unified under one joint government until it can apply for Federation-membership. However, there were potential exceptions, such as the Kes.
