Theta 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.
