After Worlds Collide 

Earth is destroyed in a collision with the rogue planet Bronson Alpha, with about a year of warning enabling a small group of survivors to build a spacecraft and escape to the rogue planet’s moon. Continuing the story of When Worlds Collide, the novel tells of the survivors’ progress on their new world, Bronson Beta, and their conflict with other groups of survivors.
