580 Selene is a minor planet orbiting the Sun. The name Selene is that of an ancient Greek goddess of the Moon.

This body orbits the Sun nearly mid-way between the orbits of Mars and Jupiter. The orbital eccentricity is slightly lower than that of Mars. Based on its light curve, Selene has an estimated rotation period of 0.3947±0.0004 days, or just under 9.5 hours.[1] During each rotation, the apparent magnitude varies by 0.27. The approximate diameter of this asteroid is 46 km.[2] (Some sources list a diameter of up to 56 km.) The albedo is about 7%, comparable to that of the Earth's Moon.
