(Found) asteroids as penal colonies

[sciencefictioninreallife]

Looking for the book title and author of a book which is about a future world, where they have gone to mining asteroids and hollowing them out. In each they place closed eco systems inside and force the rotation around the sun in such a way to send them on 50yrs+ cycles around the earth. Where generations spend time on each asteroids. at first its to get rid of the scum on earth then they come up with other reasons to send people into space. Its a story about the life on these asteroids.

can you help?

Could be Brute Orbits by George Zebrowski. (That's actually in my Pile and not yet read, but it sounds close.)
