The Purple Mountain Observatory and the Department of Astronomy, Nanjing University, in Nanjing China-Research, cooperating with the Albert Einstein institute, in Hannover, Germany, put forward a model of the planar co-orbital circular restricted three-body problem, gave the equations of motion, a set of approximation formulas, and an approximate semi-analytical solution.

Saturn's moon Calypso -- Calypso is a moon of Saturn discovered by Pascu, Seidelmann, Baum and Currie in 1980 from ground-based observations. Calypso is co-orbital with the moon Tethys, and resides in Tethys' trailing Lagrangian point (L5). The moon Telesto resides in Tethys' leading Lagrangian point. ----- Orbital radius: 294,660 km Diameter: 26 km (34 x 22 x 22) Mass: Unknown Orbital period: 1.8878 days Orbital inclination: 0 ----- NASA Learn more on this...

Telesto is a small Trojan moon of the sixth planet from the sun, Saturn. Telesto, which was discovered in 1980 by Smith, Reitsema, Larson and Fountain, is one of around 200 natural satellites in Saturnian orbit. It is one of only 62 moons that have a secure orbit, and only one of 53 named moons orbiting the ringed planet. Telesto was officially designated S/1980 S 13 and was officially named in 1983 after the Greek sea goddess of the same name. This moon is also designated as Saturn XIII...

Saturn's moon Tethys -- Tethys is a moon of Saturn that was discovered by Giovanni Cassini in 1684. Tethys is an icy body similar in nature to Dione and Rhea. The density of Tethys is 1.21 g/cm3, indicating that it is composed almost entirely of water-ice. Tethys's surface is heavily cratered and contains numerous cracks caused by faults in the ice. There are two different types of terrain found on Tethys, one composed of densely cratered regions and the other consisting of a dark...

Saturn's moon Janus -- Janus is a moon of Saturn discovered by the French astronomer Audouin Dollfus in 1966. Dollfus is credited with the discovery of Janus but it's not really certain whether the object he saw was Janus or Epimetheus and his observations led to a spurious orbit (Walker discovered it independently but his telegram arrived a few hours after Dollfus'). Larson and Fountain determined in 1978 that there are in fact two moons sharing one orbit. This was confirmed in 1980...

Saturn's moon Epimetheus -- Epimetheus is a moon of Saturn that was probably first observed by Walker and Audouin Dollfus in 1966 when they discovered Janus, but the situation was confused since Janus is in a very similar orbit and so Walker officially shares the discovery of Epimetheus with Fountain and Larson who showed in 1978 that there were two satellites involved. The situation was clarified in 1980 by Voyager 1. Epimetheus and Janus are "co-orbital". Janus' orbital radius from...
