200,000 km is 2.3-times the diameter of a geosynchronous orbit around Earth, and nowhere near the size of the Moon's orbit. My bad!

This size starship is actually in about the same ball park as many proposed "halo" or "ring world" habitats that encircle the Earth and are connected to a series of Space Elevators around the equator.

So... not so far fetched after all, perhaps.

    Time dilation would vary along the radius of the centrifuge. The design calls for a rim speed of c-1 m/s to give a Lorentz factor of 12243. However, objects stored in the centrifuge are not... more

          It seems clear how a starship would eventually be built: First a geosynchronous station would be constructed. A single space elevator cable dropped to the surface of the Earth, and a counterbalance... more

              Below is a comparison of the sizes of a Space Elevator Ring, and a Starship Ring, neatly sandwiched between the Earth and the Moon's orbit. Image is to scale in units of km.
