The "Heliocentric Planetarium" function shows you the planets around the sun, and the "Geocentric Planetarium" function shows you the position of the planets, the sun, and the moon in the sky, as seen from Earth.
You can also visualize the phases of the Moon, the satellites of Jupiter, and the trajectory of several comets.
