A stellar system consisting of two stars orbiting about a common center of mass and often appearing as a single visual or telescope object. Also known as a double star.
Two stars revolving about each other.
A pair or group of stars that are held together by mutual gravitational attraction, often orbiting each other similarly to the way the Earth orbits the Sun. You can find some interesting examples of binary stars at APOD.
A star that is gravitationally bound to another and orbits the other star around a mutual center of mass. The majority of stars in the Milky Way Galaxy are in binary or other multistar systems.
A double star system in which the two stars are physically bound by gravity, and actually orbit each other.
a double star, each orbiting their common center of mass
a double star system in which two stars orbit each other around a central point of gravity
a pair of stars that closely orbit each other
a pair of stars that travel together, often appearing as one
a system of two stars that are gravitationally bound to each other
two stars close together in the sky; they may be gravitationally bound objects or simply a projection effect on the sky
Pair of stars bound together by mutual gravitation and orbiting their common centre of mass.
Two stars that orbit a common center of gravity. These stars often look like a single star to the naked eye. If more than two stars orbit a common center of gravity, it is called a multiple star.
Two stars revolving around a common center of gravity.
A system of two stars orbiting around a common centre of mass due to their mutual gravity. Binary stars are twins in the sense that they formed together out of the same interstellar cloud.
A double star; a system containing two or more stars, locked in constant orbit. In an eclipsing binary, one star goes behind the other periodically, changing the total amount of light we can see.
a system of two stars that orbit a common center of gravity; also known as a double star.
A binary star is really two stars that rotate around a common center of mass. About half of all stars are in a group of at least two stars.
One of a pair of stars that orbit around a common center of mass. Three types of binary stars include: visual binary stars Binary stars that are identified visually, that is, observers can see two stars orbiting each other. eclipsing binary stars Binary stars that are identified by changes in their brightness due to the stars passing in front of one another. spectroscopic binary stars Binary stars that are identified by Doppler shifts in their spectrum. These Doppler shifts indicate the presence of an otherwise unseen companion star.
A system of two stars that revolve around each other under their mutual gravitation.
a pair of stars that are gravitationally bound and in orbit about each other.
A pair of stars that orbit around each other about a common center of mass.
A binary star is a stellar system consisting of two stars orbiting around their center of mass. For each star, the other is its companion star. Recent research suggests that a large percentage of stars are part of systems with at least two stars.
