HD 70642 b is a planet that orbits the star HD 70642 at 3.23 AU distance and takes 5.66 years to revolve. This planet is a “Jupiter-twin” because it is very similar to Jupiter in our Solar System, though only three-fifths the distance, twice as massive, and two-thirds as eccentric. This planet may have systems of moons like Jupiter. This planet was discovered on July 3, 2003.
