Denkir IV

Denkir IV was the habitable fourth planet of the Denkir star system and was orbited by at least one moon.

A painting of this planet depicted it from the perspective of its moon. This painting was displayed aboard the USS Enterprise (NCC-1701-D) in the observation lounge and in guest quarters. Marla Aster also had a copy of the painting in her quarters aboard the Enterprise. 

This planet was the homeworld for various aquatic life-forms. One of these life-forms had evolved into the cetacean-type Denkiri. A phylogenetic tree of the aquatic life on this planet was printed and released to schoolrooms and labs across the Federation. (, set artwork)
