It makes sense to think that the hotter the star is, the more light it will actually put out. From coolest to hottest, star colors are Brown, Red, Orange, Yellow, Yellowish White, White, Blue White, and Blue. Brown being the coolest, blue being the hottest. So therefore, Brown would be the least luminous, blue would be the brightest. You will also see stars of the same color that look brighter or dimmer. This also has to do with the distance from us that the star is. The further away, the less light will travel close enough for us to see.

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 are advantages for loads in series?
Some advantages are that the more cells (Power sources) you add, the brighter the outcome, while in parallel the voltage is the same through out.

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

Why are some stars are brighter than the others?
Because some are larger than others and some are closer than others.
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.
Why do some stars appear bigger and brighter than others?
A stars brightness depends on two factors; its distance from us and its actual brightness (absolute magnitude). The actual brightness of a star depends on various factors, such as its mass, its temperature and its age.Consider two stars of the same actual brightness (absolute magnitude) - if one of them is much closer, then is will be brighter than the further one. It will appear brighter, even though it would be the same side by side - it can be said to be apparently brighter (higher apparent magnitude) due to its distance.A:They appear bigger and brighter because they really are bigger and brighter, but even if they are not bigger and brighter it could be because they are closer.

Why does a medium-siza star appear brighter than the others?
Because some stars are closer then the others. Maybe a star isn't so big, but if its closer then a bigger one, then it looks shinier.
Why do some stars look brighter than others?
Some stars make more nuclear fusion, or just have more energy.
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.
Why do some stars seem so brighter in the night sky than other stars?
Some are closer than others and some have more power and brightness.
How come some stars look brighter that others?
that's because some stars are closer to the earth; another reason is that some stars get more sunlight than others; another reason IS that the star might not have that much enregy
