WebA sphere is defined as a closed surface in 3D formed by a set of points an equal distance R from the centre of the sphere, O. The sphere's radius is the distance from the centre of the sphere to the sphere's surface, so based on the definition given … WebJul 20, 2006 · The Earth is at the center of the celestial sphere, an imaginary surface on which the planets, stars, and nebulae seem to be printed. On the celestial sphere, lines of right ascension and declination are similar to longitude and latitude lines on Earth. When a telescope's right-ascension axis is lined up with the Earth's axis, as shown here, the …
