- Theta_Persei abstract "Theta Persei (Theta Per, θ Persei, θ Per) is a star system 37 light years away from Earth, in the constellation Perseus. The primary star is a yellowish dwarf (main sequence) star of spectral type F7V, which is somewhat larger and brighter than our sun, but still within the range considered to have the potential for Earth-like planets. There is also a red dwarf companion of spectral type M1V, orbiting about 250 AU from the primary. The star's age is estimated to be 2.8 billion years but is certainly no less than 1.7 billion years and no greater than 3.9 billion years.Theta Persei is moving through the Galaxy at a speed of 30.5 km/s relative to the Sun. Its projected Galactic orbit carries it between 23,700 and 34,200 light years from the center of the Galaxy.Theta Persei came closest to the Sun 285,000 years ago when it had brightened to magnitude 2.99 from a distance of 21.7 light years.".
