- In Depth | Saturn Moons – NASA Solar System Exploration
The Voyager and Pioneer flybys of the 1970s and 1980s provided rough sketches of Saturn’s moons But during its many years in Saturn orbit, NASA’s Cassini spacecraft discovered previously unknown moons, solved mysteries about known ones, studied their interactions with the rings and uncovered new mysteries – including the discovery on an ocean moon with potential ingredients for life
- In Depth | Moons – NASA Solar System Exploration
The chunks of ice and rock in Saturn's rings (and the particles in the rings of the other outer planets) are not considered moons, yet embedded in Saturn's rings are distinct moons or moonlets These shepherd moons help keep the rings in line Titan, the second largest in the solar system, is the only moon with a thick atmosphere
- In Depth | Enceladus – NASA Solar System Exploration
Also, like some other moons in the extensive systems of the giant planets, Enceladus is trapped in what’s called an orbital resonance, which is when two or more moons line up with their parent planet at regular intervals and interact gravitationally Enceladus orbits Saturn twice every time Dione, a larger moon, orbits once
- In Depth | Titan – NASA Solar System Exploration
In Depth Saturn's largest moon, Titan, is an icy world whose surface is completely obscured by a golden hazy atmosphere Titan is the second largest moon in our solar system Only Jupiter's moon Ganymede is larger, by just 2 percent Titan is bigger than Earth's moon, and larger than even the planet Mercury

- In Depth | Our Solar System – NASA Solar System Exploration
Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids Beyond our own solar system, there are more planets than stars in the night sky

- Enceladus, Moon of Saturn - NASA Solar System Exploration
Enceladus (pronounced en-SELL-ah-dus) is an icy moon of Saturn with remarkable activity near its south pole Covered in water ice that reflects sunlight like freshly fallen snow, Enceladus reflects almost 100 percent of the sunlight that strikes it Because the moon reflects so much sunlight, the surface temperature is extremely cold, about –330 degrees F (–201 degrees C) The surface of

C D Gravitational tugs from Saturn’s moons -best understood ring sculptors Other things that could be sculpting the rings -Gravity of Saturn’s massive rings? -Saturn’s magnetosphere? -Sunlight?
- In Depth | Europa – NASA Solar System Exploration
Formation Jupiter’s large Galilean moons – Io, Europa, Ganymede, and Callisto – likely formed out of leftover material after Jupiter condensed from the initial cloud of gas and dust surrounding the sun, early in the history of the solar system
