HD 50554 is a star approximately 0.958 exameters away in the constellation Gemini.

Star

HD 50554 is a yellow-white main-sequence star [F8V] that currently fuse hydrogen in its core. Since the star is 7^th magnitude, it is not visible to the unaided eye, but with binoculars or a telescope, it should be easy to see this star. The age of the star is only 10 million years older than our Sun. It is a population I star with metallicity of –0.07 dex [Fe/H] or 85% as much metals as the Sun.

Planetary system

In 2002, a giant planet was found by Debra Fischer, who used the radial velocity method. This superjovian planet orbits at 341 gigameters from the star in an eccentric orbit.
