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.
What else can I help you with?
are smaller stars brighter?
No. Larger stars are generally brighter. Blue giants are the brightest stars while red dwarves are the faintest.
Are stars cooler than the sun brighter or dimmer?
Stars can be both cooler and brighter or hotter and dimmer than the Sun, depending on their size and age. Generally, larger and younger stars are hotter and brighter than the Sun, while smaller and older stars can be cooler and dimmer.
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.
How does brigthness vary from the size of the star?
Brighter stars are typically larger in size because they have more surface area to emit light and heat. The luminosity of a star depends on its size, with larger stars generally being brighter than smaller stars. However, other factors such as temperature and distance also play a role in determining a star's brightness.

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?
The big stars have more hydrogen to burn and has much more surface area thats why it shines brighter.
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.

Out of the two bulbs in the house one glows brighter than the other which one of the two has a larger resistance?
The bulb that glows brighter has a smaller resistance. This is because a larger current flows through the bulb with smaller resistance, resulting in it glowing brighter.
Why is the sun brighter than all other stars?
The sun appears brighter than other stars because it is much closer to Earth, allowing us to receive a higher amount of its light and energy. Additionally, the sun is a relatively average-sized star, so its brightness is more prominent compared to much larger or smaller stars.
Is your sun smaller or bigger than stars in the night sky?
some stars are smaller than sun remaining stars are bigger than sun.
Its Cooler larger and brighter than most main sequence stars?
red giant
