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

How can stars have different absolute brightness?
Big stars are brighter than small stars, and hot stars are brighter than cool ones.
Are stars brighter than planets?
Stars are intrinsically brighter than planets, typically. Planets (in general) shine by reflected starlight, whereas stars produce their own light. The exception are black dwarfs, which are burned out stars, and neutron stars which do not emit much light in the visible spectrum. Some planets glow a bit in the infrared from their own internal heat as well. As seen from earth Venus outshines any star, and Jupiter rivals Sirius, Arcturus, and Vega in brightness. These stars are all brighter than Mars and Saturn. The reason the planets appear brighter than some stars is because they are very close, while the stars are very, very far away.
Is the sun brighter because it is closer than the other stars?
It is better to say that the sun appears brighter because it is closer. Some stars are actually brighter than the sun.
The length of a stars life is determine by what?
By mass . The smaller the star the longer it shines. Stars that are 20 times the mass of the sun only last 10 million years or so but will be thousands of times brighter than our sun. Our sun will shine for 10 billion years (it is about half way through it's life). Small stars called red dwarfs less than a tenth of the suns mass may shine for a trillion years or more but will be less than 1/100 of our sun's brightness.
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 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.
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.
How can stars have different absolute brightness?
Big stars are brighter than small stars, and hot stars are brighter than cool ones.
How is the sun different from other stars relative to earth?
The Sun is bigger than some stars and smaller than others. It is brighter than some stars and dimmer than others. Relative to the Earth it is much closer than all other stars.
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.
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.
Are commets brighter than stars?
No. Stars generate their own light, and are far more massive than any comet. Comets don't shine at all; they merely reflect the light of the Sun. From our perspective here on Earth, some comets appear to be brighter than stars, but only because the comets are here in THIS solar system, relatively nearby, while stars are many light-years away.
What causes some stars to be brighter than others?
In absolute terms larger (more massive) stars shine more brightly than less massive ones. In relative terms (as seen from Earth) more distant stars appear dimmer than closer ones.
Are brighter than stars.?
Quasars A+
Why do some dwarf stars appear brighter than giant stars?
Because they are closer or actually brighter.
How do you use the word brighter in a sentence?
Tomorrow is going to be a BRIGHTER day. The sun is BRIGHTER today then yesterday. Some day I will shine BRIGHTER than the sun.
