A classic science fiction novel. Part of the Known Space series.

From the back of the book:
"I myself have dreamed up an intermediate step between Dyson spheres and planets. Build a ring ninety three million miles in radius - one earth orbit - which would make it six hundred million miles long. If we have the mass of Jupiter to work with, and if we make it a million miles wide, we get a thickness of about a thousand meters. The Ringworld would thus be much sturdier than a Dyson sphere.

"There are other advantages. We can spin it for gravity. A rotation on its axis of seven hundred seventy miles per second would give the Ringworld one gravity outward. We wouldn't even have to have a roof over it. Put walls a thousand miles high at each rim, aim it at the sun, and very little air will leak over the edges.

"The thing is roomy enough: three million times the area of the Earth. It will be some time before anyone complains of the crowding."

- Larry Niven

Very good book. I have a feeling I have read it before; probably when I was quite young and didn't understand a lot of the things in the book.

Couldn't put it down.
