Why are some stars brighter than others?

One reason a star can seem brighter than another star is due to how much power a star has - which can also be explained as the amount of wattage it has (think of light bulbs!).

Stars with more power (or higher wattage) will shine brighter than those with less power (lower wattage).

Why are some stars brighter than others?

Another reason is the distance of the star from the Earth. Just because a star looks brighter, doesn’t mean it actually is brighter. The more distant an object is, the dimmer it appears. Therefore, if two stars have the same level of brightness, but one is farther away, the closer star will appear brighter than the more distant star - even though they are equally bright!
