Why does star Sirius appear brighter than star pollux?
Sirius appears brighter than Pollux because it is closer to Earth and is a more luminous star. Sirius is also a hot, blue star compared to Pollux, which is a cooler, orange giant star, further contributing to the difference in brightness.
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 does rigel have brighter then Sirius?
I'm not sure exactly what detail you want, but here's a start. Rigel is a triple star system. The main star of the three is a very luminous star. It is a blue supergiant star.

Why do some dwarf stars appear brighter than giant stars?
Because they are closer or actually brighter.
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.
Do the lunar highlands appear brighter than the mare?
yes
Why planets appear brighter than the sun?
There is no "why" because they don't.
Why do stars appear brighter or dimmer?
Stars appear brighter or dimmer depending on their distance from Earth. The closer a star is, the brighter it appears, while stars that are farther away appear dimmer. Additionally, stars can also vary in brightness due to changes in their own luminosity or if they are being obscured by interstellar dust or gas.
