HIP 57050, or GJ 1148, is a faint star with two orbiting exoplanets in the northern constellation of Ursa Major.
[10] From a distance of 36 light years based on parallax measurements, it is drifting closer to the Sun with a radial velocity of -9 km/s.
[11] The spectrum of HIP 57050 matches a small M-type main-sequence star, a red dwarf, with a stellar classification of M4.0V.
It is radiating just 1.5%[7] of the luminosity of the Sun from its photosphere at an effective temperature of 3,236 K.[5] A team led by astronomer Nader Haghighipour [de] reported the discovery of a Saturn-mass planet in the habitable zone of the star in 2010.
According to Haghighipour, the detection is important because it "indicates that observational techniques are on the right track for finding habitable low-mass rocky planets similar to Earth.
