![]() Other speculative origins for the ridge include volcanoes, plate tectonics or ring debris that rained down on the moon. During the final stages of the Cassini mission, the spacecraft made a series of close observations of Saturns rings. The image is pretty, but there's also a scientific reason to watch the planet's. For a listing of all moons, see Moons of the Planets. ![]() Its unusual shape comes from ring dust particles that impact it's equatorial region as it orbits within the Roche Division. But the team also found that a similar collision between two larger moonlets could also account for the odd shape of Iapetus ( SN Online: 4/21/14), a more distant walnut-shaped moon with a pronounced ridge along its equator that has puzzled scientists since the belt’s discovery. Peeking between the rings of Saturn is the tiny saucer-shaped moon Atlas, as viewed from the Cassini spacecraft. Atlas is a small moon near the A Ring of planet Saturn. 4 In 1983 it was officially named after Atlas of Greek mythology, because it 'holds the rings on its shoulders' like the Titan Atlas held the sky up above the Earth. Leleu and collaborators focused on the smaller moons of Saturn that orbit within the planet’s rings. Atlas (moon) Atlas is an inner satellite of Saturn which was discovered by Richard Terrile in 1980 from Voyager photos and was designated S/1980 S 28. , esk, Dansk, Deutsch, English (UK), English (US), Espaol. Or they could form highly elongated rotating moons that subsequently break apart. Sky Moon Mars See sky in Google Earth Help About Google Sky Google Sky. At higher angles, for example, moonlets might hit and run. Not all run-ins create a weird looking moon. Speeds are relative to the escape velocity, the speed at which ejected material escapes the gravity of the combined moonlets.Ī. Dark areas are original moonlet surfaces, whereas in the light areas the surface has been ejected or contorted. A variety of moon shapes could result from two moonlets coming together at different angles and speeds, according to computer simulations.
