A sandy, windswept and stormy world, it was created by the nanobots who made the planet from the excess material of Red Dwarf that they didn't want. The nanobots also created a 'fake', micro-Red Dwarf for the Dwarfers to chase after between Series VI and Series VII.
The Red Dwarf planetoid is finally made back into Red Dwarf, and even improved and it's original crew resurrected (who had died in the original radiation leak), in the Series VII finale - Series VIII opener.
After the last episode of Series V, during the incident on the ocean moon containing the SSS Esperanto, Red Dwarf was stolen by the nanobots (unbeknown to them at the time), and the Boys from the Dwarf spent the next two series searching Deep Space for Red Dwarf on Starbug without Holly.
In the last episode of Series VII, they eventually find the planetoid which the nanites had turned Red Dwarf into whilst looking for Kryten's nanobots to rebuild Lister's lost arm and retracing their steps back to where they were 13 episodes ago - when they investigated the wreck of the SSS Esperanto on an ocean moon. Kryten noted that the Psi-Scan was mysteriously reading the new red planet orbiting with the same ocean moon as their long-lost mothership, with the sand comprised of what was once computer chips and so forth. Lister, the Cat and Kochanski took an armored sand buggy down to the new red planetoid investigate. Although the planetoid had gravity and it's own breathable atmosphere, the weather was dire, with hurricane force gales, and constant lightening strikes exploding on the surface.
Nonetheless in among the electrical storm they managed to scavenge pieces of junk that had undoubtedly originated on Red Dwarf, such as vending machines, the Cat's beauty aids, and an inflatable shark which was once in the sleeping quarters. Confirmation that the planetoid was Red Dwarf was found when the original, senile version of Holly was found stored in Lister's wristwatch.
Reconstruction of Red Dwarf
When caught in Lister's laundry basket, the nanites turned the planetoid back into Red Dwarf, and tried to compensate for their behavior by improving on the design of the rebuilt ship. The nanites even resurrected the original crew (who had all been killed in the radiation leak three million years ago) and also rebuilt a new version of Holly to run the new and improved ship. However, the amazement and joy of the regular characters was extremely short-lived, as the nanobots then fled, leaving them without any evidence to corroborate their story. The other, newly-resurrected crewmembers of Red Dwarf locked up the regular characters in The Tank for stealing and crashing a Starbug. ("Nanarchy", Series VII) ("Back in the Red", Series VIII)
Behind the scenes
- The set used for the surface of the Red Dwarf planetoid had been used twice before in Series VII; as the unnamed ice planet that the Kinitawowi battle cruiser crashes into in "Ouroboros", and as the charred desert planet Delta VII in "Epideme".
- The set was destroyed whilst filming the Starbug model leaving the Red Dwarf planetoid surface. Non-flammable gases were supposed to be used to depict the Starbug jet propellant, but the wrong type of gas (i.e. flammable) was accidentally used. This was then ignited by the small pyrotechnics that were meant to be depicting the lightening strikes on the surface. Footage of the accident can be seen on the Series VII DVD making-of feature.
