An annotated picture of Saturn's many moons captured by the Cassini spacecraft. Shown in the image are Dione, Enceladus, Epimetheus, Prometheus, Mimas, Rhea, Janus, Tethys and Titan. The moons of Saturn are numerous and diverse, ranging from tiny moonlets only tens of meters across to the enormous Titan, which is larger than the planet Mercury.
Titan (larger crescent) and Rhea (smaller crescent), two regular moons of Saturn. In astronomy, a regular moon or a regular satellite is a natural satellite following a relatively close, stable, and circular orbit which is generally aligned to its primary's equator.
The Moon orbiting around Earth (observed by the Deep Space Climate Observatory) A natural satellite is, in the most common usage, an astronomical body that orbits a planet, dwarf planet, or small Solar System body (or sometimes another natural satellite). Natural satellites are colloquially referred to as moons, a derivation from the Moon of Earth.
The four outer planets, called giant planets or Jovian planets, collectively make up 99% of the mass orbiting the Sun. [h] All four giant planets have multiple moons and a ring system, although only Saturn's rings are easily observed from Earth. [91] Jupiter and Saturn are composed mainly of gases with extremely low melting points, such as ...
The Moon, Io and Earth shown to scale. Although significantly smaller, some of the Solar System's moons and dwarf planets share similarities to Earth's density and temperature. The index can be calculated for objects other than planets, including natural satellites, dwarf planets and asteroids. The lower average density and temperature of these ...
The atmosphere of Titan is the dense layer of gases surrounding Titan, the largest moon of Saturn.Titan is the only natural satellite of a planet in the Solar System with an atmosphere that is denser than the atmosphere of Earth and is one of two moons with an atmosphere significant enough to drive weather (the other being the atmosphere of Triton).

The new discovery increases the moons orbiting the "jewel of our solar system" to 82, surpassing Jupiter. Skip to main content. Sign in. Mail. 24/7 Help. For premium support please call: ...
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]
