Rimmerworld is an S-3 (life supporting) planet that can be found by passing through a large orange wormhole. It supports a 'civilisation' entirely composed of clones of Arnold Judas Rimmer (hence the name). It should be noted that there is a serious time difference issue with Rimmerworld- for every hour passed on ths side of the wormhole, roughly 600 years passes on Rimmerworld.
