Brightness is related to distance.
However, from the same distance, an O class star is much much brighter than a M class star.
As a comparison, an O class star would appear about 100,000 times brighter than our Sun, whereas a M class star could appear 0.0017 dimmer than our Sun, if the Sun was replaced with each star.

∙ 11y agoAlthough most stars are red dwarfs, a few stars are quite a bit brighter than our sun. Sirius, Vega, and Altair are all much brighter than our star. Deneb is about 50,000 times as bright as our sun. Rigel, in Orion, is about 100,000 times brighter than our sun.

So the smaller the star is the less brighter it gets.

are smaller stars brighter?
No. Larger stars are generally brighter. Blue giants are the brightest stars while red dwarves are the faintest.
Why do the big stars shine brighter than the smaller stars?
The big stars have more hydrogen to burn and has much more surface area thats why it shines brighter.
Are stars really little moons?
No. Stars are much larger than planets or moons. Stars are suns, some larger and brighter than our own.
Are smaller stars closer to earth?
No, but because small stars emit less light than large ones, they are only visible to the naked eye at comparatively "short" distances in interstellar terms while larger, brighter stars are visible at much greater distances.
Are most stars are smaller or larger than the sun?
Most stars are smaller than the sun, falling into the red dwarf category.

No. Larger stars are generally brighter. Blue giants are the brightest stars while red dwarves are the faintest.
How do stars use frequencies?
The electromagnetic radiation (including light) have frequencies. Stars may also pulsate (get larger and smaller, and thus brighter and less bright) at a certain frequency.
How does the HR diagram explain why some smaller cooler stars are brighter than larger hotter stars?
In terms of absolute magnitude, a larger hotter star will necessarily be more luminous than a smaller cooler star. However, if a smaller cooler star is much closer to us than a larger hotter star, it may appear to be brighter. None of this has anything to do with the HR diagram.
Why do the big stars shine brighter than the smaller stars?

Why do stars with smaller masses burn longer than stars with larger masses?
Stars with larger masses have stronger gravity; this results in more pressure; which in turn makes the star hotter. As a result of the higher temperature, they will shine brighter, and burn their fuel much faster.
Are stars really little moons?
No. Stars are much larger than planets or moons. Stars are suns, some larger and brighter than our own.
Its Cooler larger and brighter than most main sequence stars?
red giant

How do star are more brighter than other stars?
Stars are more brighter than other stars because they have different characteristics that affect their luminosity. Luminosity is the amount of energy that a star emits per unit of time. It depends on the star's size, temperature, and distance from the observer. Some of the factors that make stars more brighter than other stars are: Size: Larger stars have more surface area and can emit more light than smaller stars. Temperature: Hotter stars have higher energy and can emit more light than cooler stars. Distance: Closer stars appear brighter than farther stars because their light has less space to travel and lose intensity.
When compared with most stars are planets brighter or smaller?
Well,planets do not have any light of their own so they are definitely not brighter and yes there may be some stars smaller than the planets but most of the stars are bigger than the planets . But on the whole the Space is not that much explored so that we can get any cumulative answer.
Why does pole star appear larger and brighter than other stars?
It doesn't. A lot of stars seem larger and brighter than it. In fact, Polaris is the 49th-brightest star in the sky. To us, it is not a particularly bright star. It is important because it seems to be still as other stars rotate around it.
Why do stars appear larger in the night sky?
When there is little light like during night time, we can see the stars more clearly. This makes them look brighter and hence, larger.
