Answer 2

The diameter is the earth around 13,000km.

• Earth is the only planet in the solar system i.e known to support life to date.
• Earth was earlier considered to be a perfect sphere in shape but scientists proved that it is an "oblate spheroid', a sphere that has poles with flattening ends.
• This flattening is due to the rotational velocity of the planet at a rate of 1,674.4 km/h eventually causing the planet to bulge at the equator.
• Because of this fact, the diameter of the earth is about 43 kilometres larger than the pole-to-pole diameter.
• The latest discovery is that the earth has an equatorial diameter of 12,756 km and a polar diameter of 12713.6 km.
• Mean diameter is often used in calculations to avoid this discrepancy of diameters i.e the sum of the polar and equatorial diameter is divided in half. Thus, the calculated mean diameter of the earth is 12,742 km.
