Translate the coordinates
« on: December 04, 2017, 05:24:48 AM »
Is it possible to translate the coordinates of the declination and right ascension of a star, as well as knowing its distance from the Earth to the system x, y, z?

Yes, itís all trigonometry. Iím not going to try to write you a trig class specifically for US≤, but I can at least state that it can be done. You need knowledge of right triangles, in other words Sine, Cosine, Tangent, and the Pythagorean theorem. Luckily, you donít know to use spherical trig. That is however needed to give moonsí orbits a specific tilt to a planetís equatorial plane.

Could you give me some source or resource, where is the training for this translation or any formulas? I understand trigonometry at the middle level.

I found the necessary formulas and I already managed to make a translation, thanks for the help.
