WebDec 31, 2024 · The answer is that scientists have spotted planets in the orbits of binary stars. A good example of this is Algieba, which consists of two stars and has a planet orbiting. The planet has been identified as a gas giant with a solid base, not a terrestrial planet like ours. WebA binary star system consists of two stars both orbiting around their barycenter.For each star, the other is its "companion star". The term "binary star" was apparently first coined by Sir William Herschel in 1802 to designate "a real double star —the union of two stars that are formed together in one system by the laws of attraction". Any two stars seen close to … WebNovae are all binary stars in which the gainer is a white dwarf. The loser can be a compact star; an M-type star that can be either a main sequence star or one that is hydrogen poor, indicative of some stripping before or during the evolution of the system; or a giant that is similar to the ones observed in symbiotic stars. how to size up and down objects in sims 4
