WebApr 9, 2024 · The Sun's radius is 695,800km, therefore, the KIC 2852336's radius is an estimated 772,338.km. If you need the star's diameter, you just need to multiply the radius by 2. KIC 2852336 Surface Gravity. The Surface Gravity of the star as measured in CGS (Centimeter-Gram-Second) is 4.355. The gravity has a relationship to its mass and radius. Webwhere h is height above sea level and R is the Earth radius . The expression can be simplified as: where the constant equals k = 3.57 km/m½ = 1.22 mi/ft½ . In this equation, Earth's surface is assumed to be perfectly spherical, with R equal to about 6,371 kilometres (3,959 mi). Examples [ edit]

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 km … 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 … See more 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. … 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 The first published reference to the Earth's size appeared around 350 BC, when Aristotle reported in his book On the Heavens that mathematicians had guessed the circumference … 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 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 … See more WebGalaxy effective radius or half-light radius ( ) is the radius at which half of the total light of a galaxy is emitted. [1] [2] This assumes the galaxy has either intrinsic spherical symmetry or is at least circularly symmetric as viewed in the plane of the sky. phoenix windows iom
