Expert Solution
Concept and Principle:
  • When studying a celestial object we use two types of magnitudes. The apparent magnitude and absolute magnitude.

 

  • The absolute magnitude is the magnitude of a celestial object if it was observed from a distance of 10 parsecs.

 

  • The apparent magnitude of a celestial object is the brightness measured by an observer at a specific distance from the object.

 

  • The two magnitudes and distance to the object are related by,

m−M=5log10(d)-5

Here d is the distance to the celestial object, m is the apparent magnitude, and M is the absolute magnitude.
