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.
Why does a medium-siza star appear brighter than the others?
A medium-sized star may appear brighter than other stars due to its luminosity, which is a measure of the total amount of energy it emits per unit time. This brightness is determined by factors such as the star's size, temperature, and distance from Earth. In general, larger and hotter stars tend to be more luminous and thus appear brighter in the night sky.
Is the sun brighter than most stars?
The sun is a very small star is not as bright or big as most other stars but it seems bigger and brighter because it is much closer. Some stars have burned out, but we still see them in the night sky because the light they give off takes so long to reach us. There may even be some stars that have gone through their entire life cycle but we still have no idea of their existence because they are so far away! The night sky is fascinating, isn't it?
Why are some of the stars very faint?
Some stars appear faint because they are located far away from Earth, making them difficult to see with the naked eye. Others may be faint due to their size and temperature, emitting less light compared to brighter stars. Dust and gas clouds in space can also block or dim the light from stars, making them appear fainter.
When viewed from earth a red star and a blue star can appear to be equally bright what can you infer about these two stars?
In the case of an occulting binary star system. You have two stars that orbit each other. When one star passes between the other star and the observer it blocks (or occults) the farther one thus decreasing the amount of light to the observer by the brilliance of the farther star. This only happen if both stars and the observer are so aligned to end up on the same straight line at some point.
What is the past tense of some stars appear to be brighter than others?
'Appear' would become 'appeared' in the past tense so the sentence would simply be 'some stars appeared to be brighter than others'.
Why are some stars are brighter than the others?
Because some are larger than others and some are closer than others.
Why do some stars look brighter than others?
Stars look brighter than others due to factors such as their size, temperature, and distance from Earth. A larger and hotter star will appear brighter, as will a star that is closer to us. The brightness of a star as seen from Earth is measured by its apparent magnitude.
Is the sun equally bright as other stars?
No it is not. It is less bright than some, but brighter than others.
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.
Why do some dwarf stars appear brighter than giant stars?
Because they are closer or actually brighter.
Why are some stars brighter than others?
Stars appear brighter depending on their size, temperature, and distance from Earth. Larger and hotter stars emit more light, making them appear brighter. Additionally, stars that are closer to Earth will appear brighter than those that are farther 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.
Why do planets seem brighter than stars?
Some planets seem brighter - not all of them. Planets are quite near to us, as compared to the stars.
Why do some stars seem so brighter in the night sky than other stars?
The brightness of a star depends on its intrinsic luminosity, distance from Earth, and atmospheric conditions. Stars appear brighter if they have high luminosity, are closer to Earth, or if they are visible in a clear, dark sky away from light pollution.
Why do some starts appear brighter than others?
The brightness of stars varies because of many reasons. 1. The Distance. Some Stars are far away, and the light takes longer to reach us, so the star only appears to be darker then stars around it that may appear brighter. 2.The size. Some stars are massive, and appear brighter then others simply due to their size. 3. It isn't a star. what you may be looking at isn't a star. You may be seeing a satellite, quasar, or even a close white dwarf or neutron star. 4. Finally, you may be looking at the milky way. in which case, they all appear to be brighter then stars outside it. This also falls under distance.
What makes some stars look brighter then others?
How big, how hot (color/amount of energy emitted), how far, light pollution at viewing site
