Hi there, I’m Robert and I’m going to tell you about spinning and orbiting planet Earth. Did you know that the room you are in right now is actually moving at a huge speed? Not only is the Earth spinning, but the Earth is also orbiting around the Sun at about 30 km/s, and the Sun is moving around the centre of the Milky Way galaxy at 20,000 km/s and the galaxy is ... but let's concentrate on the spinning Earth first.
Even at 30 km/s (that's over 100,000 kilometres an hour) the Earth still takes a year to go all the way around the Sun.
None of the nine planets in the solar system orbits the Sun in a circle. Their orbits are elliptical - like a slightly squashed circle shape.
