What was this old space show called?

This has been bugging me for awhile now! Here are the details of this
show.
-It took place in space, pretty sure the shit was big and a bright
colour like orange or something!

-One main commander

-A two-headed person, they were classified as the "Unintelligent ones"

Please help.. It's an old cartoon. Pretty sure between the late 80's
up to the 90's
