HD 33564 b is an extrasolar planet located approximately 68 light-years away in the constellation of Camelopardalis.

This planet orbits around F6V star HD 33564.

HD 33564 b is a gas giant in a habitable zone of its star.

Based on a probable 10−4 fraction of the planet mass as a satellite,[1] it can have a Mars-sized moon with habitable surface.

[2] On the other hand, this mass can be distributed into many small satellites as well.
