HIP 14810 is a G-type main-sequence star located approximately 170 light-years away[1] in the constellation of Aries.

Planetary system[edit]

Orbiting the star are three confirmed planets. The discovery paper for HIP 14810 b and HIP 14810 c was published in 2007,[3] while that for HIP 14810 d was published in 2009, together with a revision for the orbital parameters for planet c.[4]
