If we could move the Earth, how far away from the Sun would it need to be to maintain a temperature similar to what we have now when it becomes a red giant? How large would the Sun apear in the sky? Would the sky still be blue? Would everything have a red tint to it? I was thinking about this on the way to work today. I think it would make a nice picture to show the Earth's landscape with a huge red star in the sky. I'm learning 3dstudio and this is something I may try. I would like to have some accuracy though instead of just guessing.
