HD 96700 is a star in the equatorial constellation of Hydra. It has an apparent visual magnitude of 6.51, which puts it below the limit that can be seen with the naked eye by a typical observer. (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. It is drifting further away with a radial velocity of 12.8 km/s.
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°. 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.
HD 96700 is a G-type main sequence star with a stellar classification of G0 V. It has the same mass than the Sun and a lower metallicity. The estimated size is 114% that of the Sun. The effective temperature of the star's outer atmosphere is 5,878 K, giving it the yellow-hued glow of a G-type star. It has an estimated age of 6.8 billion years.
Together with the proper motion companion CD-27 7781, HD 96700 make a wide binary system. At an angular distance of 6,867", the projected separation between both stars is of 174,000 AU (2.75 light-years). The companion is a K-type main-sequence star of K6V spectral type. The existence of any additional stellar companions at projected distances from 7 to 209 astronomical units is ruled out.
