In contrast, many moons and rings orbit each of the jovian planets. Neptune also has a ring system, but it is not as well observed as those of the other planets. Although there are other Jovian planets have rings, they are not as illustrious, and are often hard to see. The below false-color image from radar mapping of Titan's surface shows features that are proposed to be lakes of liquid on Titan's surface. Jupiter's ring system is made up of three parts: the gossamer rings, the halo ring and the flat main ring. The chemical composition of Titan's atmosphere and its temperature and pressure have led astronomers to propose that there may be bodies of liquid methane and/or ethane the size of lakes on the surface and it may rain liquids that are similar to gasoline. Uranus' Moons include Juliet, Cressida, Bianca, Portia, Puck, Belinda, Rosalind, and Desdemona. Each planet has a large system of moons which are in orbit around it. No satellite mission since the Voyager 2 mission has visited these moons, though, so their properties are not as well studied yet as the Galilean satellites and Titan. How does the number of rings for the Jovian planets compare to that of the Terrestrial planets? Thus, if a small object orbiting the Sun happens to pass too close to Jupiter, it can become captured into an orbit around Jupiter.
