AI overview

Luminosity is the total amount of electromagnetic energy that a star or other astronomical object emits per unit of time—essentially, how much light and energy it radiates into space. Astronomers use this measurement to compare the intrinsic brightness of different objects, such as the Sun, which serves as a reference point called one solar luminosity.
