1. The equatorial radius is about 30.7 % greater than the polar radius. 2. The value for the equatorial radius is defined to the nearest 0.1 m in WGS-84. 3. Due to its rapid rotation, the primary has a polar radius about and an equatorial radius of about. 4. This is of course related to the fact that the polar radius is about 21 kilometers less than the equatorial radius 5. Assume that the spheroid, an ellipsoid of revolution, has an equatorial radius a and polar semi-axis b. 6. Where " M " and " R e " represent the mass and mean equatorial radius of the body. 7. And a and b are the equatorial radius ( semi-major axis ) and the polar radius ( semi-minor axis ), respectively. 8. The new flattening estimate was one part in 298.257 222 101 and the equatorial radius was 6, 378, 136.8 metres. 9. :: : : If the Earth were a sphere, you would just multiply the equatorial radius by the cosine of the angle of latitude. 10. For comparison, the equatorial radius of the planet Jupiter is 71, 492 km, which is 65 % as large as Wolf 359's.
