Web11 de abr. de 2024 · If m 1 and m 2 are the magnitudes of two stars, then we can calculate the ratio of their brightness ( b 2 b 1) using this equation: m 1 − m 2 = 2.5 log ( b 2 b 1) or b 2 b 1 = 2.5 m 1 − m 2. Here is another way to write this equation: b 2 b 1 = ( 100 0.2) m 1 − m 2. Let’s do a real example, just to show how this works. Web19 de jan. de 2024 · Right Ascension and Declination. The key to creating a 3D model of the visible stars are three measures: Distance, Right Ascension, and Declination. Such a model holds the Sun in the center (at point 0,0,0). Distance, therefore, is the distance from the Sun to the star being mapped. The other two are somewhat more difficult to understand.
