Saturn in context

Planets are massive enough to pull themselves round and to have cleared their orbit of other debris — the second part is the line the solar system's dwarf planets fall short of.

At 116,460 km across, Saturn is 9.1 times the diameter of Earth.

Its mass is 95 times the mass of Earth.

It keeps an average distance of 9.58 AU from the Sun, so sunlight takes 80 minutes to reach it.

A single orbit takes 29 years.

An average temperature of 134 K works out at -139 degrees Celsius, colder than the 15 degrees Earth averages.

293 moons are known to orbit it.
