Question

Cutter is a star with an apparent magnitude of –1 and an absolute magnitude of –5. casper is a star with an apparent magnitude of –1 and an absolute magnitude of 0. use this information to answer the next questions.which of the stars is closer to earth?

Answer 1

To solve this problem you must apply the proccedure shown below:
 1. The formula for calculate the distance in parsecs to a star, which is:
 d=10^[(m-M)+5)/5]
 Where m is the apparent  magnitude and M is the absolute magnitude.
 2. Therefore, you have:
 - Distance of Cutter:
 d=63.09 parsecs
 - Distance of Casper:
  d=6.30 parsecs
 Therefore, the answer is: Casper.
