Let's do the math	by Control	2007-05-18 02:21:29
Earths current land surface is around 150'000'000 square km. Let's assume the ring were in geosynchronous orbit (which it by no means has to be), a bit more than 35'500 km up: It's a cylinder, with a radius of 35'500 + 6'300, or about 42'000 km. the circumference is therefore 84'000 * pi, or about 260'000 km. So in order to have equal surface area as the whole of earth landmass, it'd only have to be around 600km wide.
