'''HD 32963''' is a G-type main sequence star located 124 light years away from Earth<ref>{{Cite web|date=2019-04-22|title=HD 32963 b - NASA Science|url=https://science.nasa.gov/exoplanet-catalog/hd-32963-b/|access-date=2025-05-21|language=en-US|website=science.nasa.gov}}</ref> in the constellation of Taurus. It has a mass of 0.94 solar masses. It is 4.99&nbsp;billion years old.<ref name="exoplanet">{{Cite web |last=Martin |first=Pierre-Yves |date=2021 |title=Planet HD 32963 b |url=https://exoplanet.eu/catalog/hd_32963_b--2494/ |access-date=2025-05-21 |website=exoplanet.eu |language=en}}</ref> It has one exoplanet orbiting it which was discovered using radial velocity. The exoplanet that has been named HD 32963 b is a Jupiter analogue due to its similar characteristics to the planet Jupiter such as orbit and size.<ref name="iopscience"/>

==Planetary system== It has one currently discovered exoplanet orbiting it, named HD 32963 b. The planet orbits the star at a distance of 3.41 AU with an eccentricity of 0.07. It takes 2372 days to orbit the parent star. It has a minimum mass of 0.7 Jupiter masses; in 2023 its inclination was measured by astrometry, showing it to have a true mass about twice that of Jupiter.<ref name=Xiao2023/> The orbit and size of HD 32963 b is similar to the planet Jupiter. This makes it a Jupiter analogue planet.<ref name="exoplanet"/><ref name="iopscience"/>
