relative "brightness" is based on distance, size, and temperature
No. Stars vary greatly in size and brightness.
Variable stars and main sequence stars can have similar brightness. Variable stars, like Cepheid variables, can fluctuate in brightness over time, while main sequence stars maintain a relatively stable brightness due to their fusion processes.
The color of a star indicates its surface temperature. Blue stars are hotter, while red stars are cooler. This temperature affects the star's brightness and behavior.
A star's brightness is known as its magnitude. Stars with lower magnitude numbers are brighter than stars with a higher magnitude number.
Temperature of stars is indicated by their color, with blue stars being hotter than red stars. Brightness of stars is indicated by their luminosity, which is how much light a star emits.

No. Stars vary greatly in size and brightness.
The actual brightness of stars, known as their intrinsic luminosity, depends primarily on their temperature, size, and energy output. Hotter and larger stars emit more energy and therefore appear brighter. Additionally, the composition of a star, including its age and the presence of elements, can also influence its luminosity. Ultimately, a star's brightness is a combination of these factors, along with its distance from Earth, which affects how we perceive its brightness from our vantage point.

Not necessarily. Two stars can have the same brightness but be at different distances from Earth. The distance of a star affects how bright it appears to us, so a closer dim star may appear as bright as a farther bright star.

Magnitude.
Brightness corresponds to amplitude of waves. Greater amplitude means greater brightness (so lower amplitude means less brightness).
The brightness is very similar to the temperature, the brightness relies on the temperature
Size and temperature determine the brightness of stars.
