story identification - Scifi novel where a boy named Jobs is sent into space in a spaceship to avoid an asteroid

There was a science fiction book from my childhood, about a boy named Jobs, who is sent in a spaceship with other people to a new world after earth is hit with an asteroid and destroyed.

I think it was a 10 to 12 part series. There also was an Asian girl named two-face.

Sorry I can't remember more, but I was 5 when I read this book.
