Thousands of years ago, people spent hours gazing at the night sky. They found that by connecting the stars as if they were dots, patterns emerged that resembled animals, people and things.

Today, we call star patterns constellations. Eventually, 88 star patterns were identified. The patterns helped people navigate on land and by sea as well as tell time, appearing in different parts of the sky depending on the day and year. (The stars don't move. Earth moves, rotating on its axis once every 24 hours and revolving around the Sun once every year.)
