    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.
