        Very big!

        It weighs about 6000000000000000000000000 kilograms – which I can’t even image.

        If you laid it flat (like on a world map) it measures 7,926 miles across.

        Still it not as big as the Sun. You could fit over one million Earth’s into the Sun!

        The volume of the earth is 1,083,000,000,000 km3
        This is the same as 433,000,000,000,000,000 olympic swimming pools

        The earth is larger than Mercury, Venus and Mars, but smaller than Jupiter.

        The circumference (distance around the Earth) is
        40075 km.
        Thats about the same as running 950 marathons!

        The human population on Earth is about 7.2 billion.
