HD 85859 is a single star in the equatorial constellation of Hydra. It has an apparent visual magnitude of 4.88, which is bright enough to be visible to the naked eye. The distance to this star, as estimated from its annual parallax shift of 12.6 mas, is 259 light years. It is moving away from the Earth with a heliocentric radial velocity of 50.5 km/s. The stellar classification of the visible component is K2+ III CN0.5, which matches an evolved K-type giant star with a mild overabundance of CN in the atmosphere. At the age of 4.34 billion years, it is a red clump star, which indicates it is on the horizontal branch and is generating energy through helium fusion at its core. The star has 1.55 times the mass of the Sun and is radiating 178 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,415 K. (en) HD 85859 är en ensam stjärna belägen i den södra delen av stjärnbilden Vattenormen. Den har en skenbar magnitud av ca 4,88 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 2 på ca 12,6 mas, beräknas den befinna sig på ett avstånd av ca 259 ljusår (ca 79 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 51 km/s.
