Crew fact file

The Sun is a star at the centre of our Solar System. Its visible surface is about 5.5 thousand °C. Eight planets travel around it: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Jupiter is the largest planet. Mars looks reddish because iron-rich dust covers much of its surface. Earth takes about 365 days to orbit the Sun. Earth has one natural moon, called the Moon. Saturn is famous for its broad rings, made mostly of ice and rocky pieces. Uranus is the coldest planet by average atmospheric temperature, although Neptune is farther from the Sun.
