List of unnamed Delta Quadrant planetoids.
Unspecified planetoids[]
Specific plantoids[]
Dark matter nebula planetoids[]
In 2371 the USS Voyager encountered several planetoids inside a dark matter nebula that the Komar called their home. (VOY: "Cathexis")
Delta Flyer crash site[]
This class M planetoid in an unnamed star system had a bemonite mantle and several active volcanoes. In 2375, an ion storm caused the Delta Flyer to crash on this planet. Afterward, Voyager recovered the craft and the people aboard and warped away before the storm reached them. (VOY: "Once Upon a Time")
According to the Star Trek: Star Charts (p. 90), this system was named FGC-521443.
Hazari trap[]
This planetoid was discovered by Voyager in 2375. While they believed it was rich in dilithium, it was actually a trap set by the Hazari. Once they came close enough to it, it exploded and created a metreon cloud that Voyager was trapped in. (VOY: "Think Tank")
Vidiian planetoid[]
This rogue class M planetoid was thought to be an extremely rich source of dilithium, the biggest deposits ten to twenty kilometers inside the planetoid. This was an illusion created by the power source of a hidden Vidiian facility. The planetoid also contained a system of subterranean caves with an oxygen-nitrogen atmosphere.
Neelix first visited the planetoid some three years before 2371. In 2371, he lead USS Voyager to the planetoid. Unfortunately while under the surface, his lungs were stolen by Vidiians Dereth and Motura. Voyager then beamed him up and chased the Vidiians to a neutronium asteroid. (VOY: "Phage")
The planetoid was also referred to as a planet and a moon.
