HD 96700 is the Henry Draper Catalogue designation for a star in the equatorial constellation of Hydra. It has an apparent visual magnitude of 6.51,[2] which puts it below the limit that can be seen with the naked eye by a typical observer.[8] (According to the Bortle scale, it is possible for some observers to see it from dark rural skies.) Based upon parallax measurements, this star is around 83 light years away from the Sun.[1] It is drifting further away with a radial velocity of 12.8 km/s.[2]
This is considered a high proper motion star, shifting its position across the celestial sphere at a rate of 0.52 arc seconds per year, along a position angle of 255.21°.[9] It is a member of the thin disk population of stars and is orbiting the galactic core at a mean galactocentric distance of 23.4 kly (7.17 kpc) with an orbital eccentricity 0.16. The inclination of its galactic orbit carries it no more than 950 ly (290 pc) away from the galactic plane.[10]
HD 96700 is a G-type main sequence star with a stellar classification of G0 V.[3] It has a slightly lower mass than the Sun[4] and a lower metallicity.[3] The estimated size is similar to the Sun, ranging from 96% to 110% depending on the method used.[5] The effective temperature of the star's outer atmosphere is 5,879 K,[3] giving it the yellow-hued glow of a G-type star.[11] It appears to be much older than the Sun, with age estimates ranging up to 11.9 billion years.[6]
A 2015 survey ruled out the existence of any additional stellar companions at projected distances from 7 to 209 astronomical units.[12]
