    HD 70642 b is an exoplanet orbiting the star HD 70642 at a distance of 3.23 AU, taking 5.66 years to complete an orbit. This planet may have systems of moons like Jupiter. [1] This planet was discovered on July 3, 2003. It is located about 95 light-years away in the constellation Puppis. In 2023, the inclination and true mass of HD 70642 b were determined via astrometry. [2]
