Because its father away than the rest.
'Appear' would become 'appeared' in the past tense so the sentence would simply be 'some stars appeared to be brighter than others'.
Our sun is about average compared to other stars. Some are much smaller (white dwarfs) and others are much larger.
the color of the hottest star is blue
Because in eclipsing binaries, the two stars orbit each other regularly passing in front of the other, blocking out some or all of light of the hidden star.
Because some are larger than others and some are closer 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.
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.
'Appear' would become 'appeared' in the past tense so the sentence would simply be 'some stars appeared to be brighter than others'.
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.
Yes, though not all stars are the same. Some stars are bigger and brighter than the sun, some smaller and dimmer, and others about the same. The sun is only of significance to use because it is much closer than any other star.
Our sun is about average compared to other stars. Some are much smaller (white dwarfs) and others are much larger.
Stars emit light in all colours (some more than others) but these combine and appear white to the human eye.

Some stars are actually bigger than others, and some are closer to us, so appear bigger. The biggest star is UY Scuti, which is 1708 times bigger than the sun. It is 7800 light years away. The closest is Alpha Centauri, at 4.5 light years away. Note: nearly all stars are so far away that they still appear as just points of light, even in large telescopes. The angular size of some stars can be measured using "interferometry".
some stars seem smaller than the other because they are further away from earth. many stars are also located in different galaxies and are very bright therefore making it slightly visible.
Average like the sun ... about 10 billion years. But most stars are dimmer and so live longer, some much longer.
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.
