A star's apparent brightness depends on:* Its actual brightness - please note that there are huge differences here.
* Its distance. If one star is 10 times as close as another one, it will appear to be 100 times as bright.
* Any dust or gas that may absorb part of the star's light.

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.
Why does the sun appear brighter than a star?
The Sun is much, much closer to the Earth than any other star - eight light minutes vs. four light years for the next nearest star.
Why is the sun appear brighter than alpha centauri b?
Our Sun appears brighter than Alpha Centauri B because of its proximity to our point of view. We are much closer to our Sun then any other star which means that our Sun will be much brighter then everything else in the sky.
Why is Jupiter in the night sky brighter than betelgeuse?
Jupiter is brighter than Betelgeuse in the night sky because it is much closer to the Earth in comparison to Betelgeuse(Betelgeuse is more than 500 lightyears away form the Earth). This way, Jupiter appears larger than Betelgeuse, and celestial objects that appear larger also appear brighter than objects that appear small.
What would be brighter star than -1?
There is no such thing as a star with a magnitude brighter than -1. Negative magnitudes indicate brighter objects, with the most negative magnitudes corresponding to the brightest objects in the sky.
What makes some stars appear brighter than others the temperature or the size?
It is a mixture of both. A hotter star will generally appear brighter than a cooler star of the same size. Similarly, a large star will appear brighter than a small one of the same temperature. The brightest stars are generally red supergiants, which are comparatively cool stars, but are so large that their size more than makes up for it. A star's apparent brightness from any given vantage point also depends on its distance. The closer a star is to you, the brighter it will appear.
How can you tell if a star is brighter than another?
The star might be closer to the Earth, or it is just brighter than the others. :D
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.
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 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.
Why would one red giant appear brighter than the other?
Three possibilities: It is brighter (some are brighter than others), it is bigger, or it is closer to earth.
What are the factors that make one star appear brighter than another star?
The size of the star, because the smaller the star the hotter it is because of nuclear fusion. So the hotter the 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.
A bright star can appear dimmer than a less bright star if the bright star is?
If the bright star is located farther away from Earth than the less bright star, it will appear dimmer due to the inverse square law of light intensity. The amount of light reaching Earth decreases with distance, so a closer, less bright star can appear brighter than a further, brighter star.
Why Some stars appear to shine more brightly than the others?
The stars vary in both how far away they are and in actual brightness. The closer a star is to us, the brighter it will appear. Stars also vary in actual brightness. For example, the brightest star in the night sky is Sirius. It appears bright because it is both a fairly bright star (about 25 times brighter than the sun) and is one of the closest stars to us at 8.6 light years away. The nearest star visible in the night sky, Alpha Centauri, is about half that distance but does not appear as bright because it is far less bright than Sirius in actual luminosity. Conversely, Sirius also appears brighter than Betelgeuse which is actually much brighter than Sirius but also much farther away.
What is a brighter star?
A star that is brighter than another.
Why one star may appear brighter than other star?
One star may appear brighter than another star due to several factors, including its size, temperature, distance from Earth, and luminosity. A larger, hotter, closer, or more luminous star will typically appear brighter in the night sky compared to a smaller, cooler, more distant, or less luminous star.
