Sample text

The second describes the other bodies of The Solar System, comets and asteroids, in this small part of space where everything revolves around the Sun. Section three focuses on The Stars, especially the dramatic ending of their lives, sometimes resulting in supernovae explosions and the formation of pulsars or black holes. In The Milky Way lie explanations of the objects in the night sky, and how millions of stars organize into galaxies. Section five, The Universe, gathers the current knowledge of what we know of the beginning of time, of the Big Bang, and of the ancestors of stars and galaxies.

Many of Saturn’s smaller moons, such as Phoebe, have orbital characteristics that suggest that they were originally asteroids that have been captured by Saturn’s gravity. 3-SECOND BANG Saturn – the furthest of the planets known to humankind since antiquity – is best known for its spectacular ring system and varied retinue of moons. 3-MINUTE ORBIT Saturn’s rings are composed of chunks of ice and rock, the debris of a small moon shattered by gravitational forces 100 million years ago. Extending around 6,400–120,700 kilometres (4,000–75,700 miles) above Saturn’s equator, the rings are only 100 metres (325 ft) thick.

It has the lowest density of all the planets – less dense than water on Earth. Its deep atmosphere is composed of hydrogen and helium wrapped around a small rocky core; the atmosphere is squashed outwards by fast rotation to make it 10 per cent wider at the equator than at the poles. Differences in the observed spin rate of features suggest that a day on Saturn is 25 minutes longer at the poles than at the equator. Saturn has more than 60 moons – ranging from tiny moonlets less than a kilometre across to the gigantic Titan, which has a diameter of 5,150 kilometre (3,200 miles) and is larger than the planet Mercury.
