The one doing the revolving is the "orbiting object".
It doesn't usually get more specific than that, unless one is referring to a moon or man-made object in orbit around a planet. Those are called satellites.
Other orbiting objects include the planets of a solar system around their sun, and the electrons of an atom around its nucleus.
Such an object could be a terrestrial planet, a dwarf planet, or an asteroid.
