Constellations & Asterisms

A constellation is an area in the sky containing a group of stars that looks like a particular shape. Throughout history, constellations served to navigate the sky, and until now astronomers use their names to point out the sky objects’ locations. The International Astronomical Union formally acknowledges 88 constellations. Some smaller groups of stars are called asterisms – they also have particular shapes, but are composed of stars that are already part of a bigger constellation. The most famous asterism is the Big Dipper, a part of the constellation Ursa Major. Here, we provide detailed articles, colorful infographics, and interesting quizzes on constellations and asterisms.
