Real Life Information
The Groombridge Star System, also known as Groombridge 1618 and Groombridge 34, is a real binary star system located in the constellation Ursa Major. It is named after the British astronomer Stephen Groombridge, who cataloged it in his "A Catalogue of Circumpolar Stars."
Groombridge 1618 is located approximately 15.9 light-years away from Earth, making it one of the nearest star systems to our own. It is a binary star system, meaning it consists of two stars orbiting a common center of mass. The two stars in the Groombridge 1618 system are both red dwarfs, which are the most common type of star in the Milky Way galaxy.
The primary star, Groombridge 1618 A, is a red dwarf of spectral type K7.5V. It has about 40% the mass of the Sun and 42% its radius. Despite its smaller size, it is brighter than most other red dwarfs due to its relatively high metallicity. The star is also known to be a flare star, which means it can undergo sudden increases in brightness due to magnetic activity.
The secondary star, Groombridge 1618 B, is a much fainter red dwarf of spectral type M2V. It has about 14% the mass of the Sun and 16% its radius. The two stars orbit each other at a distance of about 147 astronomical units (AU), which is roughly the distance from the Sun to the dwarf planet Eris in our own solar system.
The Groombridge 1618 system is of particular interest to astronomers because of its proximity to Earth and the fact that it contains two relatively bright red dwarfs. This makes it an excellent target for studies of stellar astrophysics and potentially habitable exoplanets. However, as of now, no planets have been detected in the system.
The Groombridge 34 system, on the other hand, is located in the constellation Andromeda and is approximately 11.7 light-years away from Earth. It is also a binary star system, with both stars being red dwarfs. The primary star, Groombridge 34 A, is of spectral type M1.5V, while the secondary star, Groombridge 34 B, is of spectral type M3.5V. The two stars orbit each other at a distance of about 147 AU.
The Groombridge 34 system is notable for being the third closest known solitary star system to the Sun, after Proxima Centauri and Barnard's Star. It is also known to host at least one exoplanet, Groombridge 34 Ab, which was discovered in 2014.
