1.) Constellations are useful. They help astronomers and other observers orient in the night sky. The star Betelgeuse, for example, is Orion's right shoulder. Betelgeuse is the eighth brightest star in the sky.
2.) Constellations are useful because they help stargazers and astronomers recognise specific stars in the night sky. Today, constellations are less important than they were in Ancient History. In Ancient times, constellations were used to create and track the calendar so they knew when to plant crops and harvest them.
3.) Are the stars in a constellation near each other? Not necessarily. Each constellation is a collection of stars that are distributed in space in three dimensions – the stars are all different distances from Earth.
