F Hydrae, also known as HD 74395, is a star in the constellation Hydra with an apparent magnitude is 4.64. It was catalogued as 31 Monocerotis, but this name is now rarely used since the star is now within the boundaries of Hydra. It is a low mass yellow supergiant around a thousand times brighter than the sun and five times as massive. F Hya is a catalogued as a triple star, with 8th magnitude BD-06°2707 80" away and 13th magnitude companion at 57". (en) HD 74395 (F Hydrae) é uma estrela na direção da Hydra. Possui uma ascensão reta de 08h 43m 40.38s e uma declinação de −07° 14′ 01.4″. Sua magnitude aparente é igual a 4.63. Considerando sua distância de 604 anos-luz em relação à Terra, sua magnitude absoluta é igual a −1.71. Pertence à classe espectral G2Ib. (pt) 31 Monocerotis är en gul superjätte i Vattenormens stjärnbild. Trots sin Flamsteed-beteckning tillhör den inte Enhörningens stjärnbild. Den ligger på gränsen mellan stjärnbilderna och fick byta tillhörighet vid översynen av gränser mellan stjärnbilderna år 1930 och benämns efter bytet av stjärnbild ofta med sin HD-beteckning, HD 74395. Den har också Bayerbeteckningen F Hydrae. 31 Monocerotis har visuell magnitud +4,63 och är synlig för blotta ögat vid normal seeing. Den befinner sig på ett avstånd av ungefär 770 ljusår.
