Why does star Sirius appear brighter than star pollux?
While Pollux is actually brighter than Sirius, Sirius appears brighter because it is several times closer.
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.
Which is brighter larger stars or smaller stars?
Brightness is related to distance. However, from the same distance, an O class star is much much brighter than a M class star. As a comparison, an O class star would appear about 100,000 times brighter than our Sun, whereas a M class star could appear 0.0017 dimmer than our Sun, if the Sun was replaced with each star.
