Best Answer

It depends on the distance between the Earth and Jupiter. Since Jupiter is much further away from the sun than the Earth, it takes longer for it to make a rotation around the sun. This difference in the speed at which the two planets orbit the sun leads to differences in their distance to one another over the span of months and years. Generally of course the closer the two planets are from one another, the greater brightness that Jupiter appears to us.

The reflectivity of its clouds change but mostly it is because of the varying distances between it and the earth that cause it to dim or brighten in our sky.

No. The stars are not only not the same brightness, they are not the same distance from us - they just "appear" to be as part of the optical illusion of earthbound astronomy. They are all of varying brightness, though fairly close in brightness overall.
