Orders of magnitude

Orders of magnitude is a way to talk about very big or very small numbers. It helps us to compare numbers that are too big or too small to fit into one sentence. For example, the number of stars in the sky is really big. We can say that it is many thousands or millions or even billions of stars. That is like saying it is many orders of magnitude bigger than the number of animals in your house. That means that the number of stars is way bigger than the number of animals in your house.
