HD 44219 b is an extrasolar planet which orbits the G-type main sequence star HD 44219, located approximately 164 light years away in the constellation Monoceros. This planet has at least three-fifths the mass of Jupiter and takes 1.29 years to orbit the star at a semimajor axis of 1.18 AU. However unlike most other known exoplanets, its eccentricity is not known, but it is typical that its inclination is not known. This planet was detected by HARPS on October 19, 2009, together with 29 other planets.
