}}{{Starbox end}}HD 96819 is a variable star[18] in the constellation of Hydra. It was formerly known by its designation 10 Crateris, but that name fell into disuse after constellations were redrawn and the star was no longer in Crater. Its apparent magnitude is 5.43.[3] Parallax measurements by Hipparcos put it at
This is a quickly rotating A-type main-sequence star that is about 2 times as massive as the Sun. It emits 20.66 times as much energy as the Sun, at a surface temperature of 8,954 K. HD 96819 is currently 31.5% through its life as a main-sequence star: after that it will swell up as a red giant.[4]
