Kelemane's planet (aka "The Weird Planet Displaced in Time") was a planet in the Delta Quadrant. Tuvok described the planet as having, "gravimetric readings similar to that of a collapsed dwarf star and a rapid rotation rate like a quasar". It was also unusual due to its tachyon core, which generated a subspace particle field that ran between the poles. When USS Voyager encountered the planet in 2376, it was pulled into its orbit by a gravimetric gradient. The ship disrupted the field, causing high-frequency seismic activity on the surface.
