Page 3 - Revolve and Rotate: An Earth's story
P. 3
You see the Earth is always in motion, being pulled and pulling.
Our Sun is in the centre of the solar system pulling all the planets with its gravitational pull forcing
them to revolve around it. It takes some planets longer than others to travel and make their way
around the sun. But for Earth it takes 365 days or one year to make the journey.
