One recently discovered moon, Aegaeon, resides within the bright arc of G Ring and is trapped in the 7:6 mean-motion resonance with Mimas. [27] This means that it makes exactly seven revolutions around Saturn while Mimas makes exactly six. The moon is the largest among the population of bodies that are sources of dust in this ring. [51]
Rhea is the second largest moon of Saturn, but with a mean diameter of 1,528 kilometers (949 miles) it is less than a third the radius of Saturn's largest moon, Titan. Rhea is an icy body with a density of about 1.236 g/cm 3. This low density indicates that it is made of ~25% rock (density ~3.25 g/cm 3) and ~75% water ice (density ~0.93 g/cm 3).
Pan is the innermost named moon of Saturn. [4] It is approximately 35 kilometres across and 23 km wide and orbits within the Encke Gap in Saturn's A Ring. Pan is a ring shepherd and is responsible for keeping the Encke Gap free of ring particles. It is sometimes described as having the appearance of a walnut, or raviolo. [5]
Saturn’s moon Enceladus may have all the ingredients necessary to host life, according to a new study based on data from Nasa’s Cassini spacecraft mission.. The spacecraft ended its mission in ...
Aegaeon is the smallest known moon of Saturn outside of the rings and has an extremely elongated shape, measuring 1.4 km × 0.5 km × 0.4 km (0.87 mi × 0.31 mi × 0.25 mi) in size. [9] Measurements of its mass show that Aegaeon has a very low density, likely due to a highly porous and icy interior structure. [ 5 ]
Phosphates have been found on Saturn’s moon Enceladus, in a new breakthrough discovery that boosts hopes for finding alien life in our solar system. It is the first time phosphorus has been ...
Phoebe (/ ˈ f iː b i / FEE-bee) is the most massive irregular satellite of Saturn with a mean diameter of 213 km (132 mi). It was discovered by William Henry Pickering on 18 March 1899 [9] from photographic plates that had been taken by DeLisle Stewart starting on 16 August 1898 at the Boyden Station of the Carmen Alto Observatory near Arequipa, Peru.
Earth's moon is almost ten times larger. An underground ocean would make up about half of Mimas' volume, but it would only be equivalent to 1.2% to 1.4% of the liquid water oceans present on Earth.
