There is a storm on Jupiter that is the same size as Earth. In fact, Jupiter can hold about 1,300 Earths inside it. The Sun is about 10 times bigger than Jupiter, and about 109 times bigger than our planet. But, even in our galaxy, there are stars that are HUNDREDS of times bigger than our Sun. And our Sun, which is the centre of so much of our thinking, and is difficult to think there is much more to space than just it, is just one of more than 100 BILLION stars in our Milky Way galaxy.
