Khwopa was a bog planet inhabited by the Khwopians. It had at least one moon.
A Starfleet report described first contact with the planet as "a little tricky."
In 2380, Starfleet dispatched the USS Cerritos under the temporary command of Captain Amina Ramsey to repair the waste pipe of a water filtration system on Khwopa. (LD: "Much Ado About Boimler")
