Detailed explanation-1: -Some stars are closer and some are farther away. The closer a star is to us, the brighter it will appear. Also, stars come in a variety of sizes and brightnesses. Larger stars usually shine more brightly than smaller stars do.
Detailed explanation-2: -Apparent magnitude (or brightness) depends on the location of the observer. Different observers will come up with a different measurement, depending on their locations and distance from the star. Stars or objects that are closer to Earth, but fainter, could appear brighter than far more luminous ones that are far away.
Detailed explanation-3: -The distance to the star. For two stars of identical size and temperature, the closer one to us will appear brighter. An analogy is a row of street lights, the closer ones appear much brighter than those in the distance.
