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.
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.
What affects the brightness of stars?
relative "brightness" is based on distance, size, and temperature
Temperature and brightness of stars are indicated by what?
by me and you
What do you call the stars which increases their brightness by exploding and suddenly growing brilliantly?
Supernova

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.
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.
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.

Is shape affects the brightness of the stars?
no
What is the measure of a stars brightness?
Magnitude.

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.
