HD 28254 b (also known as HIP 20606 b) is an exoplanet which orbits the G-type main sequence star HD 28254, located 180 light-years away in the constellation Dorado.
[1] Due to the planet's high mass, it is assumed to be a gas giant like Jupiter.
Since HD 28254 b was detected indirectly, properties such as its inclination, radius, and temperature are unknown.
HD 28254 takes about 3 years to orbit its host and has one of the most eccentric orbits around a star.
In 2023, the inclination and true mass of HD 28254 b were measured via astrometry, though the mass remains uncertain - it is between about 1.6 and 6.8 times the mass of Jupiter.
