A star's spherical coordinates are often expressed as a pair, right ascension and declination, without a distance coordinate. The direction of sufficiently distant objects is the same for all observers, and it is convenient to specify this direction with the same coordinates for all. In contrast, in the horizontal coordinate system, a star's position differs from observer to observer based o… Webof the two-body problem to write a system of polynomial equations for the topocentric distance and the radial velocity at the two epochs. We define two different algorithms for the computation of the solutions, based on different ways to perform elimination of variables and obtain a univariate polynomial. Moreover we use the redundancy of the WebFeb 12, 2024 · The current Right Ascension of The Moon is 20h 48m 18s and the Declination is -23° 50’ 48” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom ).
