WebNov 28, 2024 · The altitude of a satellite is the distance between the Earth's surface and the satellite, but the Earth itself is not spherical. At the equator the Earth's radius is 21 km more than at the poles, and in fact the shape of the Earth is not even a perfect oblate spheroid. So how is the altitude of a satellite actually defined? WebThe term APSL means above present sea level, comparing sea levels in the past with the level today. Earth's radius at sea level is 6,378.137 km (3,963.191 mi) at the equator. It is 6,356.752 km (3,949.903 mi) at the poles and 6,371.001 km (3,958.756 mi) on average. [3] Measurement [ edit]
WebThe radius and period of the Moon’s orbit was measured with reasonable accuracy thousands of years ago. From the astronomical data in Appendix D, the period of the Moon is 27.3 days = 2.36 × 10 6 s, and the average distance between the centers of Earth and the Moon is 384,000 km. Solution Solving for M E , WebThe constant of proportionality, G, is the gravitational constant.Colloquially, the gravitational constant is also called "Big G", distinct from "small g" (g), which is the local gravitational field of Earth (equivalent to the free-fall acceleration).Where is the mass of the Earth and is the radius of the Earth, the two quantities are related by:
WebEarth radius. Since the Earth is flattened at the poles and bulges at the equator, geodesy represents Earth's shape with an oblate spheroid.

WebA low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, with an altitude never more than about one-third of the radius of Earth.. The term LEO region is also used for the area of space below an …
WebThe radius of orbit indicates the distance that the satellite is from the center of the earth. Now that the radius of orbit has been found, the height above the earth can be calculated.
