Earth radii unit
WebThe radius of Earth is approximately 6371km. Its mass is about 5.972 ⋅ 10 24 kg. Applying the equation gives us a surface gravitational field strength of 9.81m/s 2. Moon. The radius of the Moon is approximately 1737km. Its mass is about 7.348 ⋅ 10 22 kg. Applying the equation yields a surface gravitational field strength of 1.62m/s 2. Mars. The Earth's meridional radius of curvature at the equator equals the meridian's semi-latus rectum: b 2 / a = The Earth's prime-vertical radius of curvature at the equator equals the equatorial radius, N = a. The Earth's polar radius of curvature (either meridional or prime-vertical) is: a 2 / b = Derivation 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.
