HD 44219 is a solar-type star with an exoplanetary companion in the equatorial constellation of Monoceros. It has an apparent visual magnitude of 7.69, making it an 8th magnitude star that is too faint to be readily visible to the naked eye. The system is located at a distance of 173 light-years from the Sun based on parallax measurements, but is drifting closer with a radial velocity of −12 km/s. In 2009, a Jovian planet was found in a highly eccentric orbit around the star by the HARPS planet search program. There is some evidence of an additional, longer-period companion.

  • HD 44219は、いっかくじゅう座の方角に約172光年の距離にある8等級のG型主系列星である。この恒星は太陽と比べて大きく、明るく、質量や表面温度はほぼ同じである。また、金属量は太陽より若干多い。また、スペクトル型は太陽のG2Vと一致している。 (ja)
  • HD 44219 är en ensam stjärna belägen i den sydöstra delen av stjärnbilden Enhörningen. Den har en skenbar magnitud av ca 7,70 och kräver åtminstone en stark handkikare eller ett mindre teleskop för att kunna observeras. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 19,8 mas, beräknas den befinna sig på ett avstånd på ca 164 ljusår (ca 50 parsek) från solen. Den rör sig närmare solen med en heliocentrisk radialhastighet på ca -12 km/s. (sv)
