5 godz. temu · For the purpose of measurement, the Sun's radius is considered to be the distance from its center to the edge of the photosphere, the apparent visible surface of the Sun. By this measure, the Sun is a near-perfect sphere with an oblateness estimated at 9 millionths, which means that its polar diameter differs from its equatorial diameter by ...

In 1827, Carl Friedrich Gauss made a distinction between the intrinsic and extrinsic properties for surfaces in 3-dimensional space. A property of a surface is extrinsic if might change when a map that preserves local distance measurements, called a local isometry, is applied to it.

5 godz. temu · The Moon is Earth's only natural satellite.It orbits at an average distance of 384,400 km (238,900 mi), about 30 times the diameter of Earth. Tidal forces between Earth and the Moon have over time synchronized the Moon's orbital period (lunar month) with its rotation period at 29.5 Earth days, causing the same side of the Moon to always face Earth. . The Moon's gravitational pull – and to a ...
