How are artificial satellites like New Horizons steered in space?

I based this one on common sense, really.
There's no fluid in space, obviously, meaning the rudders aren't going to do anything at all in space. So, no for that.
There's no steering equipment on the satellites. Again, choose no for that.
By changing the direction of the wheels? Seriously? SERIOUSLY?
By ejecting some mass into space sounds the most plausible. Imagine a see-saw. If you put more mass on one side and less on the other, then this would cause it to drop to that side. Similarly applying this logic to ejecting mass in space, more mass on one side of the satellite causes it to drop/veer the satellite.
