because they are different sizes and different distances away from earth
The brightness is very similar to the temperature, the brightness relies on the 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.
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
Probably because they are the closet to us!
Size and temperature determine the brightness of stars.
the moon can vary its brightness and the pink elephant called aphadophalis
While stars share similarities in that they are massive, luminous celestial bodies fueled by nuclear fusion, their temperatures and brightness can vary greatly. Stars can range in temperature from thousands to millions of degrees Kelvin, affecting their color and spectral characteristics. Similarly, their brightness, or luminosity, is influenced by factors such as size, mass, and stage of evolution. Therefore, not all stars are similar in terms of temperature and brightness.
