Saturn
The second biggest planet in the Solar System
Saturn
- 764 times as big in volume as earth and measure 75,000miles in diameter.
- takes 29½ years to travel around the Sun.
- complete orbit is a journey of nearly 3 billion miles.
- winds ten times stronger than a hurricane on Earth swirl around Saturn’s equator, reaching up to 1,125 mile per hour (mph).
- Saturn is not solid – made of gases and liquids; almost entirely hydrogen and helium.
- only in the planets’s very small core is there any solid rock.
- As Saturn is so big – the pressure deep inside is enough to turn hydrogen gas into a liquid; further down – extreme pressure makes the liquid hydrogen act like a metal.
- one of the fastes-spinning planets – rotates in just 10.66 hours; this means that it spins at nearly 22,000 mph.

Spacecraft ProbeÂ
- the surface of Saturn appears smooth because the clouds are hidden under a layer of a haze.
- the Cassini probe has spotted lightening storms and a huge swirling storm near the pole.
- the Cassini probe went into orbit around Saturn in 2004 for a four-year study of its clouds, rings and moons. It carried the Huygens probe, which dropped through the atmosphere of the largest moon, Titan, onto a surface so cold that the pebbles were made of solid ice.
