When the solar system settled into its current formation, around 4.5 billion years ago, gravity pulled together swirling clouds of gas and dust to create the third planet from the Sun; Earth. Like its fellow terrestrial planets, Venus, Mercury, and Mars, the Earth has a central core, a rocky mantle, and a solid crust. Earth's rocky core formed first, with heavy elements colliding and binding together. Dense material sank to the centre, while the lighter material created the crust. Earth's magnetic field, which protects us from harmful solar radiation, its also thought to have formed around this time. Planet Earth is currently the only astronomical body known to support life.
