1). Some stars are brighter or dimmer than others.
2). Some stars are nearer or farther from earth than others.
So any given star can be bright and near, bright and far, dim and near, or dim and far.
It's kind of like the reason why some instruments in the band sound louder than others.
A piccolo has to be a lot nearer to you in order to sound as loud as a far-away Trumpet.

What are the two factors that determine how bright a star looks from earth?
The two factors that determine how bright a star looks from Earth are its intrinsic brightness, or luminosity, and its distance from Earth. Stars that are more luminous will appear brighter, while stars that are closer to Earth will also appear brighter.
Why are we not able to see stars other than the sun during the day?
We are unable to see stars other than the Sun during the day because of the Earth's atmosphere scattering sunlight. This scattering causes the sky to appear bright and blue, which overshadows the faint light from distant stars. While stars are still present in the sky, their light is too weak to be visible against the brightness of the daytime sky.
What is the real color of stars in space?
stars come in a variety of colors. red, bright blue, yellow like our sun and even white. stars come in many different sizes too from 10 times the size of our sun to the size of a small island.
Planets always shine brighter than stars?
Planets do not always shine brighter than stars; their brightness varies depending on their position relative to Earth and the Sun. Planets reflect sunlight, making them appear bright, but their visibility can fluctuate based on factors like distance and alignment. Some stars can outshine planets significantly, especially in cases of particularly bright stars or during certain astronomical events. Overall, while planets can be bright, they are not inherently brighter than all stars at all times.
Why are stars brighter than the sun?
Most stars are dim red dwarfs which we cannot see. Most of the stars we can see actually ARE brighter than our sun. From our perspective, because we are so close to it, the sun appears big, the same reason a 100 watt light bulb in the same room appears brighter than stadium lights four miles away.
Why do stars appear yellow?
Stars appear yellow because of their surface temperature. When a star is at a medium temperature, it emits a mix of colors that our eyes perceive as yellow. Stars cooler than the Sun appear more red, while hotter stars appear more blue.
What is the brightness of a nebula?
The brightness of a nebula can vary significantly depending on its type and distance from Earth. Emission nebulae, which glow due to ionized gases, can be quite bright and visible to the naked eye, while reflection nebulae appear less bright as they scatter light from nearby stars. Dark nebulae, on the other hand, are not bright at all and are often seen as silhouettes against the background stars. The overall brightness is influenced by factors such as the nebula's size, composition, and the intensity of the light sources nearby.
Why are some star appear big or small in your eyes?
It depends on the size, distance, and luminosity of a star. Our Sun looks quite big in the sky compared to other stars but only because it is so much closer. It is actually quite small compared to others but they are a much greater distance away. And lastly, dim stars can be close to Earth but don't appear very big or bright because they don't give off much light.
Why do some stars look bigger than the other stars?
Some stars appear bigger than others due to their intrinsic luminosity, distance from Earth, and atmospheric effects. Brighter stars or those closer to Earth may appear larger in the sky, while atmospheric distortion can also make stars seem larger than they actually are.
Can you tell planets from stars using the naked eye?
The planets are orbiting the sun continuously, meaning their positions are changing. Jupiter, Mars, Venus and Saturn are the easiest to see when they are visible, as they appear very bright. Mercury can be seen, but is too close to the sun usually to be clearly seen. The others are very far away, so not very bright. Currently, Jupiter is best to see and easy to find. It can be seen as a very bright object towards the south, for a few hours after sunset. Regularly check out Heavens Above, which is the site linked to below, which will help you to find the different planets and much more in the night sky.
Which property of a star can be determined by its color?
The temperature of a star can be determined by its color. Hotter stars appear blue/white, while cooler stars appear red.
Why are stars yellow?
Some stars appear yellow because either they are yellow or the white color can appear different. The spectral types F and G (our sun), contain yellow stars. This is caused by their temperature.
