If you believe scientist, who say our sun will burn out in 6 billion years, then it would be 6 billion years. Because when the sun dies it will take all the planets with it. This process is called a "nova" Don't worry about it, humans will be long gone before that happens.

There is a fascinating book called "The Earth Without Us" by Alan Weisman that deals with this very issue.  I haven't finished the book yet, so I don't know what he concludes is the last remains, but you should check it out for yourself.
