Prometheus / prəˈmiːθiːəs / is an inner satellite of Saturn. It was discovered on 24 October 1980 from images taken by the Voyager 1 probe, and was provisionally designated S/1980 S 27. [ 6 ] In late 1985 it was officially named after Prometheus, a Titan in Greek mythology. [ 7 ] It is also designated Saturn XVI.
Mimas, also designated Saturn I, is the seventh-largest natural satellite of Saturn. With a mean diameter of 396.4 kilometres or 246.3 miles, Mimas is the smallest astronomical body known to be roughly rounded in shape due to its own gravity.
Aegaeon (moon) Aegaeon / iːˈdʒiːɒn /, or Saturn LIII (provisional designation S/2008 S 1), is a natural satellite of Saturn. It has an extremely elongated shape whose surface is thought to be similarly smooth as Methone. [6] It orbits between Janus and Mimas within Saturn's G Ring.
Saturn is a gas giant, composed predominantly of hydrogen and helium. It lacks a definite surface, though it is likely to have a solid core. [ 37 ] The planet's rotation makes it an oblate spheroid —a ball flattened at the poles and bulging at the equator.
S/2019 S 1 is a natural satellite of Saturn. Its discovery was announced by Edward Ashton, Brett J. Gladman, Jean-Marc Petit, and Mike Alexandersen on 16 November 2021 from Canada–France–Hawaii Telescope observations taken between 1 July 2019 and 14 June 2021. [1]
Janus (moon) Janus / ˈdʒeɪnəs / is an inner satellite of Saturn. It is also known as Saturn X. It is named after the mythological Janus. This natural satellite was first identified by Audouin Dollfus on December 15, 1966, although it had been unknowingly photographed earlier by Jean Texereau.
Surtur / ˈsɜːrtər / or Saturn XLVIII (provisional designation S/2006 S 7) is a natural satellite of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt, Jan Kleyna, and Brian G. Marsden on June 26, 2006 from observations taken between January and April 2006.
