it depends upon 3 factors,1-the distance from the earth, 2-size of star and 3-age of the star.
Brightness is defined as a correlation between luminosity and distance. So it will depend on what is brighter and what is nearer to us.
No. Stars vary greatly in size and brightness.
the brightness of a star
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 stars you see in the sky depend on the time of year and your location on Earth. The brightness of the stars, the presence of any natural or artificial light pollution, and atmospheric conditions also influence the visibility of stars in the sky.
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.
Magnitude.
no
The brightness is very similar to the temperature, the brightness relies on the temperature
Size and temperature determine the brightness of stars.
the moon can vary its brightness and the pink elephant called aphadophalis
