Is that an egg shape?

The Earth's shape is very close to an oblate spheroid, although the precise shape (the geoid) varies from this by up to 100 metres (327 ft). The average diameter of the reference spheroid is approximately 12,742 km (more roughly, 40,000 km/π). The rotation of the Earth causes the equator to bulge out slightly so that the equatorial diameter is 43 km larger than the pole to pole diameter. The largest local deviations in the rocky surface of the Earth are Mount Everest (8,850 m above local sea level) and the Mariana Trench (10,924 m below local sea level). Hence compared to a perfect ellipsoid, the Earth has a tolerance of about one part in about 584, or 0.17%. For comparison, this is less than the 0.22% tolerance allowed in billiard balls. Because of the bulge, the feature farthest from the center of the Earth is actually Mount Chimborazo in Ecuador.
