Question
The Luminosity of a star is?
- How bright a star is
- How cool a star is
- What type of star it is
Solution
The luminosity of a star refers to the total amount of energy that a star emits per unit of time. It is a measure of a star's output energy and is often used in astronomy to classify stars. It is not a measure of how bright a star appears to observers on Earth, which is a star's apparent magnitude. Nor is it a measure of a star's temperature (how cool or hot a star is). Lastly, while luminosity can help scientists determine what type of star it is (like a dwarf star, giant star, supergiant star, etc.), it is not a direct measure of a star's type.
