HD 32963 is a G-type main sequence star located 124 light years away from Earth[8] in the constellation of Taurus. It has a mass of 0.94 solar masses. It is 4.99 billion years old.[9] 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.[3]
Planetary system
[edit]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. Its 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.[5] The orbit and size of HD 32963 b is similar to the planet Jupiter. This makes it a Jupiter analogue planet.[9][3]
