Primus IV

Memory Beta, the wiki for licensed Star Trek content.

Primus IV was a planet located in or near Federation space.

In early 2376, the USS Enterprise-E was assigned to perform a low-gravity science study on the planet, with the aid of Lieutenant Melora Pazlar, a native of another low-gravity planet. Unfortunately, before the survey could begin, the Enterprise was drawn to Pazlar's homeworld, Gemworld, to assist in an ecological disaster. (TNG novels: Gemworld; TTN novel: Taking Wing)
