Epsilon Cancri is a bright star in the cluster. DX Cancri is another red dwarf and flare star. A dynamical analysis shows that the system has to be almost coplanar in order to be stable for the age the system. With an apparent visual magnitude of 14.81, [2] it is much too faint to be seen with the naked eye.Visually viewing this star requires a telescope with a minimum aperture of 16 in (41 cm). I'm sorry, but I don't know its surface temperature, despite a quick look on "Wikipedia". Based on the spectral type, we can deduce that the surface temperature of the star is in the order of between between 5,000 and 6,000K based on the notes from Harvard University. DX Cancri is the variable star identifier for a small star in the northern zodiac constellation of Cancer the crab. Like other types of star, red dwarfs may be accompanied by planets. Visually viewing this star requires a telescope with a minimum aperture of 16 in (41 cm). A faint red Star Spectral Type M6.5V and it is a Flare Star (Variable Star) Achernar A and DX Cancri are both main sequence stars.
