Alpha Prime is the destination of the Jupiter 2 in the Lost in Space 1998 movie. The United Global Space Force and the Global Sedition both wanted to colonize this world. It takes 10 years to reach this world from Earth. The mission of the Jupiter 2 was to travel to this world and construct a Hypergate similar to the one orbiting Earth, providing instantaneous access to the planet for colonists
The script states that the planet also has an abundance of Dimondium, a substance that could help restore a dying Earth. The unproduced sequel movie would have featured the Jupiter reaching Alpha Prime, only to discover that it had already been colonized by the Global Sedition.
