EX Hydrae is a variable star classified as an eclipsing intermediate polar-type cataclysmic variable, specifically of the DQ Herculis type.[1] The system varies in apparent magnitude from 9.6 to 14.[2] The system consists of a white dwarf primary and an M-type secondary, of masses of Шаблон:Solar mass and Шаблон:Solar mass respectively.[3] The orbital period is 98.25696 minutes (0.068233846 days).[4] The system is 65±11 parsecs distant, making EX Hya one of the closest cataclysmic variable stars.[5] The cataclysmic outbursts appear to be caused by accretion of material from the M-star to the white dwarf.[4]

EX Hydrae also possess a 67-minute oscillation, believed to be caused by the spin period of the white dwarf component.[4] EX Hydrae's outbursts are unpredictable.
