HD 44219 and Its Lone Known Planet
HD 44219 is a star 173 light-years away, and it is known to host one planet. The star is a G2 V main-sequence dwarf, making it Sun-like in class, with a mass of 1 solar masses, a radius of 1.32 solar radii, and a temperature of 5750 K. Its reported radius estimate is larger than the Sun's, while its reported temperature is cooler than the Sun's.
The single known planet is HD 44219 b, discovered in 2010 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. HD 44219 b has a mass of 184 Earth masses, larger than Earth's, and it completes one orbit every 472 days.
