- Nu_Hydrae abstract "Nu Hydrae (ν Hya, ν Hydrae) is a star in the constellation Hydra, near the border with the neighboring constellation of Crater. It has an apparent visual magnitude of 3.115, which is bright enough to be seen with the naked eye. Based upon parallax measurements, this star is located at a distance of about 144 light-years (44 parsecs) from the Earth.The spectrum of this star matches a stellar classification of K0/K1 III, where the luminosity class of 'III' indicates this is a giant star that has exhausted the supply of hydrogen at its core and evolved away from the main sequence. The radius of this star has expanded to 21 times the Sun's radius with an emission of about 151 times the luminosity of the Sun. This expanded outer envelope has an effective temperature of about 4,335 K, giving it the characteristic orange hue of a K-type star.Nu Hydrae is an X-ray emitter with an estimated luminosity of 6.6 × 1028 erg s−1 in the X-ray band. The abundance of elements other than hydrogen and helium, what astronomers term the star's metallicity, is about half that in the Sun. It has a relatively high proper motion across the celestial sphere, suggesting that it has a peculiar velocity roughly three times higher than its neighbors.Nu Hydrae was a latter designation of 4 Crateris.".
