Sentences with phrase «apparent magnitude»

The phrase "apparent magnitude" refers to how bright a celestial object appears from Earth. It is a measure of how much light an object emits or reflects. The higher the apparent magnitude, the dimmer the object appears, while a lower apparent magnitude means the object appears brighter in the sky. Full definition
