Saturn’s Moons – Frame 3
About the Object
- DistanceDistanceThe physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs.The semi-major axis of Saturn's orbit about the sun is 9.5 Astronomical Units (A.U.) or roughly 1.4 billion km.
- DimensionsDimensionsThe physical size of the object or the apparent angle it subtends on the sky.The planet (without rings) has a diameter of roughly 75,000 miles (120,000 km) at the equator.

Hubble Sees Moons Racing Across Saturn
This movie still captures the moons Mimas, Enceladus, and Dione as they begin their race across Saturn's disk. The still is from a movie created from images taken by NASA's Hubble Space Telescope. It reveals the planet's rings tilted nearly edge-on toward the Sun, an event that...
Hubble Catches Titan Chasing Its Shadow
This movie still shows Titan chasing its shadow across Saturn's disk. The still is from a movie created from images taken by NASA's Hubble Space Telescope. It reveals the planet's rings tipped nearly edge-on toward the Earth. This edge-on alignment happens once every 15 years....
Saturn and Rings Tipped Edge-On Toward Earth
This time-lapse sequence shows the moons Titan and Tethys orbiting Saturn when the planet's rings were tilted nearly edge-on toward Earth. This edge-on alignment happens once every 15 years. The last time this alignment occurred was in 1995 and 1996. In the movie, the moons can...
Showcase of Saturn and Rings Tilted Edge-On Toward the Sun
This time-lapse movie shows the icy moons Mimas, Enceladus, Dione, and Tethys rounding Saturn when the planet's rings were tilted nearly edge-on toward the Sun. This edge-on alignment occurs once every 15 years. The rings' shadow appears as a thin, almost invisible line across...
Saturn's Rings at Maximum Tilt
In March 2003, Saturn's rings were at maximum tilt toward Earth, a special event occurring every 15 years. With the rings fully tilted, astronomers get the best views of the planet's Southern Hemisphere. They took advantage of the rings' unique alignment by using Hubble to...
