bases are great for building ships and units as well.

a 500 kt base can hold 1 space yard, command and then there is 50kt left over for a missle or a sat launcher or mine layer and a cargo.

Later in the game bases are great for warp defence...

Some people will deply the base build yard on a 1500 kt base with the mine layers and sat launcher on it and build the 100 mines and sats for the warp point.

Also bases have great mounts so the 2500 kt base with ripper beams on them are quite deadly.

No they cannot move.

I usually place 3 to 5 bases above my home worlds and have them build ships ( colony ships )

And where I have fleet training going on I build about 5 or 10 of them to build units for the ships.

Also if you are in the black with resources bases allows you to build more units and ships per turn.

then when you go in the red just mothball them.

Then when times are plenty again unmothball them and build away again.

Utilizing bases is a very important aspect of the game.
