Constellations Constellations are totally imaginary objects. Made up by poets, farmers, and astronomers Purpose of constellations are to tell which stars are which

The big dipper Scientific name is Ursa Major; commonly known as Big Bear One of the most easily found constellations in the sky The Big Dipper was also a very important part of the Underground Railroad when slaves were escaping to the North. There were songs spread among the slave population which included references to the "Drinking Gourd”.

The Little Dipper Scientific name is Ursa Minor; commonly known as The Lesser Bear Most common star in the Little Dipper is called Polaris or the North Star If you stood at the north pole, Polaris would be almost directly overhead

ORION Also known as The Hunter He is accompanied by his famous dogs: Canis Major and Canis Minor Hanging down from Orion’s belt is his sword that is made up of three fainter stars. The central star of the sword is really not a star at all. It’s called the Great Orion Nebula. It’s the most studied region by astronomers.
