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 … WebEarth: By the Numbers Discovery Date of Discovery: Unknown Discovered By: Known by the Ancients Orbit Size Around Sun Metric: 149,598,262 km English: 92,956,050 miles …

Gravitational constant - Wikipedia

A sphere. In the case of the geoid and ellipsoids, the fixed distance from any point on the model to the specified center is called "a radius of the Earth"or "the radius of the Earth at that point". [d]It is also common to refer to any mean radiusof a spherical model as "the radius of the earth". See more Earth radius (denoted as R🜨 or $${\displaystyle R_{E}}$$) is the distance from the center of Earth to a point on or near its surface. Approximating the figure of Earth by an Earth spheroid, the radius ranges from a … See more The following radii are derived from the World Geodetic System 1984 (WGS-84) reference ellipsoid. It is an idealized surface, and the … See more The Earth can be modeled as a sphere in many ways. This section describes the common ways. The various radii derived here use the notation and dimensions noted above for the Earth as derived from the WGS-84 ellipsoid; namely, Equatorial radius: a … See more Earth's diameter is simply twice Earth's radius; for example, equatorial diameter (2a) and polar diameter (2b). For the WGS84 ellipsoid, that's respectively: • 2a = 12,756.2740 km (7,926.3812 mi), • 2b = 12,713.5046 km (7,899.8055 mi). See more Earth's rotation, internal density variations, and external tidal forces cause its shape to deviate systematically from a perfect sphere. Local topography increases the variance, resulting in a surface of profound complexity. Our descriptions of Earth's surface must be … See more Geocentric radius The geocentric radius is the distance from the Earth's center to a point on the spheroid surface at See more The mathematical expressions above apply over the surface of the ellipsoid. The cases below considers Earth's topography, above or below a reference ellipsoid. As such, they are topographical geocentric distances, Rt, which depends not only on latitude. See more WebEarth radius (denoted as R 🜨 or ) is the distance from the center of Earth to a point on or near its surface. Approximating the figure of Earth by an Earth spheroid, the radius ranges from a maximum of nearly 6,378 km (3,963 mi) (equatorial radius, denoted a) to a minimum of nearly 6,357 km (3,950 mi) (polar radius, denoted b)..
