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 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.
Which is brighter larger stars or smaller stars?
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.
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 Pollux brighter than Castor?
It's a close call, but Pollux is brighter. Pollux has an apparent magnitude of 1.15 whereas Castor has an apparent magnitude of 1.96.(Note: the smaller the apparent magnitude the brighter it is)

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.

Which star is brighter one with a 6.3 magnitude or one with a magnitude of 1.4?
The smaller numbers indicate brighter stars. Also, a negative magnitude is even brighter than zero magnitude.
Why sun is a star?
The Sun is just like other stars - some are bigger, some are smaller, some are brighter or less bright - but the Sun is similar in size, composition and behavior to stars. The only difference is that it is so near that it looks much, much brighter.

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.
Why do some dwarf stars appear brighter than giant stars?
Because they are closer or actually brighter.
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.
