WebThe calculator below calculates Earth radius at a given latitude. In fact, of course, it calculates the radius of WGS 84 reference ellipsoid at a given latitude, and if you want some theory recap, you can find it below the calculator. Earth Radius by Latitude (WGS 84) Latitude N S Calculation precision Digits after the decimal point: 3 Calculate 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 …

WebHere x is the circumference of the earth. On solving the circumference of the earth we get 39,350 kilometres. So the radius of the earth will be. Circumference = 2πr r = 39350/ … WebThe Earth has a radius of 2.439 kilometers / 1.516 miles and a diameter of only 12.742 km / 7.917 mi. When it comes to weight, the mass of Earth is equivalent to 5.9 quadrillion … 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 maximum of nearly 6,378 km (3,963 mi) (equatorial radius, denoted a) to a minimum of nearly 6,357 … Meer weergeven 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. … Meer weergeven The following radii are derived from the World Geodetic System 1984 (WGS-84) reference ellipsoid. It is an idealized surface, and the Earth measurements used to calculate it have an uncertainty of ±2 m in both the equatorial and polar dimensions. … Meer weergeven The Earth can be modeled as a sphere in many ways. This section describes the common ways. The various radii derived here use the … Meer weergeven Earth's diameter is simply twice Earth's radius; for example, equatorial diameter (2a) and polar diameter (2b). For the WGS84 … Meer weergeven Geocentric radius The geocentric radius is the distance from the Earth's center to a point on the spheroid surface at geodetic latitude φ: Meer weergeven 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 … Meer weergeven The first published reference to the Earth's size appeared around 350 BC, when Aristotle reported in his book On the Heavens that … Meer weergeven image to graphic art
