"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 do we measure distance to stars

WebApr 25, 2024 · What unit do we use to measure distance between stars? Parsecs. Parsecs: Many astronomers prefer to use parsecs (abbreviated pc) to measure distance to stars. This is because its definition is closely related to a method of measuring the distances between stars. A parsec is the distance at which 1 AU subtends an angle of 1 arcsec. WebOct 27, 2024 · Currently, for many objects in the galaxy, and especially for molecular clouds and others not bright in the optical, astronomers determine distances by measuring their velocities and fitting them to a rotating model of the galaxy thus roughly associating velocities with the corresponding "kinematic" distances.
