Explanation: Light-year is the term used to describe the distance covered by light in a vacuum over the course of one year (which is 9.461 × 10 12 km). It is a measure of large distances used in astronomy to describe the vast distances between objects in space. × 10-5 light-years WebIf m1 and m2 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. how far ahead can i book disney world
