Good day,

I'm trying to find a way to represent a planet with the following properties:
-RADIUS
  3,980 mi (6,410 km) (equator)

  3,960 mi (6,370 km) (poles)

If anyone can help me out I would appreciate it greatly..

I'm guessing this can be done with a transformation but I don't know enough about creating / altering datums, GCSs, or projections to make this work currently.

 

Thanks in advance!
