Some multiple star systems include three stars or more, their orbits intricately intertwined by gravity. As many as seven stars have been observed in a single system. Like binaries, triple-star systems can host planets.
A star system or stellar system is a small number of stars that orbit each other, [ 1 ] bound by gravitational attraction. A large group of stars bound by gravitation is generally called a star cluster or galaxy, although, broadly speaking, they are also star systems.
ESS1.A: The Universe and Its Stars. Patterns of the apparent motion of the sun, the moon, and stars in the sky can be observed, described, predicted, and explained with models. (MS-ESS1-1) Earth and its solar system are part of the Milky Way galaxy, which is one of many galaxies in the universe.

MS-ESS1-2 Earth's Place in the Universe. Students who demonstrate understanding can: MS-ESS1-2. Develop and use a model to describe the role of gravity in the motions within galaxies and the solar system.
6 Ιουν 2018 · Alpha Centauri is a triple star system located just over four light years, or about 25 trillion miles, from Earth. While this is a large distance in terrestrial terms, it is three times closer than the next nearest Sun-like star.
MS-ESS1-1: Develop and use a model of the Earth-Sun-Moon system to describe the cyclic patterns of lunar phases, eclipses of the Sun and Moon, and seasons. MS-ESS1-2: Develop and use a model to describe the role of gravity in the motions within galaxies and the solar system.
