ETA CASSIOPEIAE is a binary system in which the two stars move in a wide eccentric orbit.  Separated by an average distance of 70 AUs, the effects from the variation of brightness and heat on the planets orbiting either star are virtually insignificant.  Although levels of heavy elements are only around half that of Sol, the outer regions of the smaller companion are rich in Tholin-X deposits.

Eta Cass A is a main-sequence yellow dwarf which is very similar to Sol and has a total of five planets in orbit.

Eta Cass B is a much cooler and dimmer orange dwarf which has several small planetoids in orbit and a dense field of asteroids and cold dust debris.
