HD 38283 b
HD 38283 b is an extrasolar planet, orbiting the 7th magnitude F-type main-sequence star HD 38283, 123 light years away in the constellation Mensa. It is a Saturn-like planet orbiting at Earth-like distance, though slightly inwards of its star's habitable zone. Its eccentricity is 0.41, much higher than the Earth's eccentricity of 0.017. The planet's distance ranges from about 0.60 AU (closer to its star than Venus is to the Sun) and 1.44 AU (nearly
similar distance from its parent star as Earth. But, given the planet's high eccentricity, and the star being more than twice as luminous as our Sun, hypothetical life on the moons may be a bit unlikely.
HD 38283 b was discovered on 11 April 2011 using the radial velocity technique using the Anglo-Australian Telescope (AAT). This method uses to look for planets by watching the star periodically wobble caused by the gravitational tug of the orbiting planets.
