'''HD 106252 b''' is a large [[Astronomy:Gas giant|gas giant]] extrasolar planet about 10 times more massive than [[Astronomy:Jupiter|Jupiter]]. It was announced in 2001 by the [[Organization:European Southern Observatory|European Southern Observatory]].<ref name="eso0114"/> The discovery was confirmed by a different team using the [[Organization:Lick Observatory|Lick Telescope]].<ref name="Fischer2002"/>

Astrometry of HD 106252 has determined an [[Astronomy:Orbital inclination|orbital inclination]] of either 46° or 134°, depending on whether the solution is prograde or retrograde. This, combined with the [[Astronomy:Minimum mass|minimum mass]], gives a true mass of {{Jupiter mass|10.0|link=y}}, larger than the [[Astronomy:Minimum mass|minimum mass]] of {{Jupiter mass|7.2|link=y}}.<ref name=Li2021/>
