Question:

Can't figure out title of book?

My Brother-in-law showed me something on the Internet of a CGI contest to make a preview for a book. I don't remember the title anymore.

It is about an asteroid suddenly orbiting around the Earth. The Americans and Russians send a ship up there. In the asteroid there is a human city, it is deserted. They find a library and they find a history book that describes the end of the earth. It said that the end of the world was the Russians and Americans fighting in nuclear war.

There was something about them finding some "former" humans on the asteroid that genetically modified themselves to their liking.

I think this book was made in the 80's or 90's. It is definitely scifi. I just don't remember the title. Please help me out here, it is stuck in my head.
