What does measurement of the brightness of a star call?
Brightness of stars (apparent and absolute magnitude) is measured by convention, taking an another star as a standard.
Do stars have the same brightness and sizes?
No. Stars vary greatly in size and brightness.
Which two groups of stars can have similar 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.
What is a stars brightness known as?
A star's brightness is known as its magnitude. Stars with lower magnitude numbers are brighter than stars with a higher magnitude number.
Temperature and brightness of stars are indicated by what?
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.
What do you call the stars which increases their brightness by exploding and suddenly growing brilliantly?
Supernova

Do stars have the same brightness and sizes?
No. Stars vary greatly in size and brightness.
What do you call two revolving stars of unequal brightness?
Two stars revolving around one another (around their center of mass, to be precise) are called a "binary star". There is no special name for the case that the brightness is unequal; this is actually the usual case.
Which two groups of stars can have similar 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.

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.
What are brighter than any single stars?
Double stars, or a Super Nova, or a comet that is close to Earth the Moon and of course Venus. The morning, evening "Star". Actually you have to distinguish between apparent brightness (as seen from Earth) and absolute brightness (as seen from a standard distance). In apparent brightness, Venus, Jupiter and Mars are brighter than any star - but their real brightness is much less. In absolute terms, some things that are brighter than single stars are groups of stars (double stars, star clusters, galaxies, galaxy clusters), exploding stars (novae, supernovae, hypernovae); and quasars.
What is the measure of a stars brightness?
Magnitude.
Is shape affects the brightness of the stars?
no
In main-sequence stars how does brightness relate to temperature?
The brightness is very similar to the temperature, the brightness relies on the temperature
What determines how bright stars are?
Size and temperature determine the brightness of stars.
