Saturn Quadruple Moon Transit | Hubble Space Telescope

This Hubble video shows four of Saturn's moons moving across the face of their parent planet on February 24, 2009. Icy moons Enceladus and Dione are on the far left, while the large orange moon Titan and icy Mimas are on the right. The closer the moon is to Saturn, the faster it orbits, according to the laws of gravity.

In astronomy, a transit (or astronomical transit) is the passage of a celestial body directly between a larger body and the observer. As viewed from a particular vantage point, the transiting body appears to move across the face of the larger body, covering a small portion of it.
