About
- Enceladus is the sixth-largest moon of Saturn (19th largest in the Solar System).
- It is about 500 kilometers in diameter, about a tenth of that of Saturn's largest moon, Titan.
Surface Temperature
- Enceladus is mostly covered by fresh, clean ice, making it one of the most reflective bodies of the Solar System.
- Consequently, its surface temperature at noon only reaches −198 °C (75.1 K; −324.4 °F), far colder than a light-absorbing body would b
- Despite its small size, Enceladus has a wide range of surface features, ranging from old, heavily cratered regions to young, tectonically deformed terrain.
Composition
- Enceladus is a relatively small satellite composed of ice and rock.
