It calculates the light emitted by stars, and how bright they are relative to their distance from Earth. The calculator takes input for a star's radius, temperature, and distance, then outputs its luminosity and magnitude, both apparent and absolute. The inputs: • Radius - Can be miles, meters, kilometers ...

The … WebOct 1, 2024 · The lifetime of a star can be calculated by measuring the star’s mass and luminosity. The mass of a star determines how much fuel it has, and the luminosity of a star determines how quickly it is using up that fuel. By measuring these two quantities, astronomers can calculate how long a star will live.
