The Earth
Our world, also known as planet Earth, is the only known planet to harbour life. It is third planet from the Sun, the densest in our Solar System and was formed around 4.54 billion years ago. The Earth spins at a staggering 1,040 mph and moves around the Sun at an incredible 30 kilometres per second. Seventy per cent of the Earth's surface is covered in water, but with the rising threat of global warming and sea level rise, this could increase.
