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.

WebMar 30, 2024 · Low Earth orbit Low Earth orbit (LEO) A low Earth orbit (LEO) is, as the name suggests, an orbit that is relatively close to Earth’s surface. It is normally at an altitude of less than 1000 km but could be as low as 160 km above Earth – which is low compared to other orbits, but still very far above Earth’s surface. WebCalculus questions and answers. A space shuttle orbits the earth at an altitude 200 km above the earth's surface, with constant speed v = 12000 km/h.
