Near the edge of this whirling mass is a middle-sized star we call the Sun, and around the Sun whirl a number of planets in a group we call the Solar System.

One of those planets is called Earth, and on Earth life formed and grew.

Earth seems like a lonely planet because while there is evidence that life could exist on other planets there is no evidence that it does.
