Omkring 50 år sedan skulle kunna vara EC Tubbs Rogue Planet från 1976. Sammanfattning från här :
Many and strange have been the adventures of Moon Base Alpha and its crew since the atomic waste pits on the dark side of the Moon exploded and sent them careering out of Earth orbit, deep into unexplored space.
Always they have managed to overcome their perils and continue their strange Odyssey. Now, at last they seem to have reached the end of the road, as caught in a weird cone of force emanating from a sentient planet, they find themselves ageing at an incredible rate and powerless to break free.
Titeln är inte helt korrekt, eftersom de inte stöter på en planet, utan snarare " en jätte grön pulserande hjärna som de kallar Omphalos "på planeten.
