Mu Hydrae es una gigante naranja de tipo espectral K4III, semejante a muchas otras estrellas brillantes del cielo nocturno —entre otras Alfard (α Hydrae), λ Hydrae y ν Hydrae, en esta misma constelación.Su temperatura efectiva es de 3999 ± 8 K y es 480 veces más luminosa que el Sol.Tiene un diámetro 45 veces más grande que el diámetro solar, igual al de Aldebarán (α Tauri), y gira sobre sí misma con una velocidad de rotación proyectada de 5,9 km/s. Mu Hydrae presenta un contenido metálico algo inferior al solar, siendo su índice de metalicidad [Fe/H] = -0,12.Por otra parte, ha sido clasificada como posible estrella variable con una fluctuación de brillo de 0,03 magnitudes.Dicha variabilidad no ha sido confirmada, recibiendo Mu Hydrae la denominación provisional, en cuanto a variable, de NSV 4528.De acuerdo a la nueva reducción de los datos de paralaje de Hipparcos, se encuentra a 234 años luz del Sistema Solar.ncuentra a 234 años luz del Sistema Solar.

Den har en skenbar magnitud på 3,83 och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 13,9 mas, beräknas den befinna sig på ett avstånd på ca 234 ljusår (ca 72 parsek) från solen.å ca 234 ljusår (ca 72 parsek) från solen.
, μ Hydrae, Latinised as Mu Hydrae, is a sol … μ Hydrae, Latinised as Mu Hydrae, is a solitary, orange-hued star in the equatorial constellation of Hydra. It is visible to the naked eye with an apparent visual magnitude of 3.83. Positioned just 1.8° to the south-southwest is the planetary nebula NGC 3242. Mu Hydrae has an annual parallax shift of 13.93 mas, which yields a distance estimate of 234 light years. This is an evolved K-type giant star with a stellar classification of K4 III, having used up its core hydrogen and has expanded to around 45 times the radius of the Sun. It is a suspected variable star, with a brightness that varies about 0.03 in magnitude. The relatively cool outer atmosphere has an effective temperature of 3999 K.re has an effective temperature of 3999 K.
