I read this in elementary school in the 90s. It’s more of a young adult book not a children’s book. There was a spaceship that people lived on and something happened, I think the ship got torn in half by an asteroid or a meteor or something like that. I think an asteroid/meteor field was coming their way, so everyone on the ship was supposed to evacuate to one side of the ship so they could seal off the middle in case of damage from the asteroid and a couple of kids or people got stuck on the side that everyone had evacuated from. They thought they were going to die but the side with all the people on it ended up being breached and everyone was exposed to space and died. So now the group of people or kids on the other side were alone. And all the controls for the ship had been on the side that got destroyed. So they try to figure out how to get rescued or land somewhere. I remember the end being very depressing. Their last hope of survival was to get their floating ruined spaceship close enough to the last planet that there were any people on, which I believe was Pluto, so that someone could essentially snag their spaceship. But they were too far away and the book ended with them floating off into space with the impression that they would starve to death. I always remember the book title having something to do with butterflies but I could be wrong. I remember the cover having a purple/ red magenta space swirl incorporated on it.
