HD 50554 b is a Jupiter sized extrasolar planet with minimum mass 4.4 times that of Jupiter, classifying as low-mass superjovian. The period of this planet is 175 weeks. The real separation between a planet from the star is 341 gigameters or 11.1 microparsecs. Combining with known distance in parsecs, the apparent separation would be about 73.5 milliarcseconds.

The planet was discovered in 2002 by four team members including Debra Fischer, who used doppler spectroscopy to measure the wobbling of the stars that’ll indicate the presence of planets caused by the planet’s gravity.
