Our story starts out in space Our Earth goes round the Sun The Sun is a Star – Our Star Stars cluster together in Galaxies And In each Galaxy there are about 100,000,000,000 Stars = 1011 Galaxies are spread across the Universe In the Universe there are 100,000,000,000 Galaxies = 1011 So - there are about 100,000,000,000 stars in each galaxy and 100,000,000,000 galaxies altogether So altogether there are 100,000,000,000 x100,000,000,000 Stars in the Universe = 10,000,000,000,000,000,000,000 1022 stars altogether This is a very BIG number 100 OOOOOOOOOOO OOOOOOOOOOO OOOOOOOOOOO OOOOOOOOOOO 10 O O O O O O O O O O O OOOOOOOOOOO OOOOOOOOOOO OOOOOOOOOOO OOOOOOOOOOO 10 100 OOOOOOOOOOO OOOOOOOOOOO OOOOOOOOOOO OOOOOOOOOOO OOOOOOOOOOO OOOOOOOOOOO OOOOOOOOOOO OOOOOOOOOOO OOOOOOOOOOO • 10,000 = 104 • • • • • • • 1000 squares • • • = 100,000 = 105 Buckminsterfullerene The Earth is 100,000,000 times larger than a soccerball 107m 10-1m 10-9m 108 108 and a soccerball is 100,000,000 x larger than a Buckyball The ratio of the size of the buckyball to the soccerball is the same ratio as the size of the soccerball to the earth
