What is the difference between brightness and luminosity? - Brightness is how it appears to us, distance is a factor. Luminosity is how much total light a star gives off. What is parallax? - Over the course of a year, the star's position in the sky appears to shift back and forth, returning to its original position 1 year later. The amount of this shift— the angle between one extreme in the star's apparent motion and the other— is equal to twice the parallax. You can use parallax to fin...
