Z Camelopardalis is a Cataclysmically Variable Star in the constellation Giraffe at a distance of about 730 light years . The system is named after the Z-Camelopardalis stars , a subgroup of the dwarf novae .
The system shows phases with strong fluctuations in the light curve and then again phases with almost constant brightness. It consists of a white dwarf and a main sequence star of the spectral class K. The fluctuations in brightness are caused by the accretion of matter from the main sequence star to the white dwarf.
