HD 50554 b is a Jupiter-sized exoplanet with a minimum mass 4.4 times that of Jupiter. The planet was announced in 2001 by the European Southern Observatory and formally published in 2002 using observations from the Lick and Keck telescopes.[1][2] In 2023, the inclination and true mass of HD 50554 b were determined via astrometry.[3]
