An asterism is a recognizable pattern or group of stars in the night sky that is not officially classified as a constellation. These patterns can be part of one constellation, span several constellations, or exist within a larger star group. Well-known examples include the Big Dipper, which is part of the constellation Ursa Major, and the Summer Triangle, formed by three bright stars from different constellations. Asterisms help observers navigate the sky, locate constellations, and identify regions of interest. They are widely used in amateur astronomy because they are often easier to recognize than full constellations.
