No. Stars vary greatly in size and brightness.
No. The stars are not only not the same brightness, they are not the same distance from us - they just "appear" to be as part of the optical illusion of earthbound astronomy. They are all of varying brightness, though fairly close in brightness overall.
No. Brighter distant stars can have the same apparent magnitude as fainter stars that are closer.(Absolute magnitude does not refer to actual brightness, but rather to what the brightness of a star would likely be at an arbitrary distance of 10 parsecs, rather than its actual distance.)
Neutral binary stars can have their sizes measured directly by photometry. By observing how the brightness of the system changes over time, astronomers can infer the sizes of the individual stars and the distance between them. This method can provide valuable information about the physical parameters of the binary system.
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.
because they are different sizes and different distances away from earth
Stars are classified by their color, temperatures, sizes, and brightness, it could also be by composition and radiation.Scientists classify stars by color, luminosity, and temperature.

stars vary greatly in the amount of light they produce
There are more than twenty-two stars in the constellation Sagittarius. Sagittarius is one of the largest constellations in the sky and contains numerous stars of varying brightness and sizes.
Both relate to brightness; both are measured in the same units; both are used for astronomical objects such as stars or galaxies.
Yes! Some stars are supergiants, which means that they are high-mass stars. They explode in a supernova towards the end of their life. These stars are generally brighter than others. A star's brightness also depends on its temperature. Red stars are the coolest temperature, followed by orange, yellow, white and blue stars.

Not necessarily. Two stars can have the same brightness but be at different distances from Earth. The distance of a star affects how bright it appears to us, so a closer dim star may appear as bright as a farther bright 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.
