HD 32963 is aG-type main sequencestar located 124 light years away fromEarth[8] in theconstellation ofTaurus. It has a mass of 0.94 solar masses. It is 4.99 billion years old.[9] It has oneexoplanet orbiting it which was discovered usingradial velocity. The exoplanet that has been named HD 32963 b is aJupiter analogue due to its similar characteristics to the planetJupiter such as orbit and size.[3]
It has one currently discoveredexoplanet 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. Its has aminimum mass of 0.7 Jupiter masses; in 2023 its inclination was measured byastrometry, showing it to have a true mass about twice that of Jupiter.[5] The orbit and size of HD 32963 b is similar to the planet Jupiter. This makes it a Jupiter analogue planet.[9][3]
