the moon can vary its brightness and the pink elephant called aphadophalis
That refers to star that change their size, and therefore their brightness, in a repetitive pattern.
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.
To learn more about the universe. For me personally, I enjoy getting outside at night and observing. I look at stars that change in brightness - variable stars - and this contributes to our ongoing long-term database.
Magnitude.
no
The brightness is very similar to the temperature, the brightness relies on the temperature
Size and temperature determine the brightness of stars.
