Question

Although a star might look brighter than the Sun, a comparison of its ______________ magnitude might help prove that they have the same real brightness.

Answer 1

Although a star might look brighter than the Sun, a comparison of its Absolute magnitude might help prove that they have the same real brightness.

Step-by-step explanation:

Apparent magnitude measures the brightness of a celestial body from the Earth at its actual position.

Absolute magnitude is the apparent magnitude of the same body when it is at a distance of 10 parsecs.

A star might look brighter than the sun but actual comparison of the brightness can be done by comparing the absolute magnitudes of the two stars.

Answer 2

Although a star might look brighter than the Sun, a comparison of its absolute magnitude might help prove that they have the same real brightness.
Absolute magnitude is a concept that compares the absolute brightness of celestial objects. The absolute magnitude of an object is defined as the apparent magnitude it would have if it were viewed at a standard distance of 10 parsecs (32.6 light-years) with no dimming of its light. The more luminous an object, the smaller the numerical value of its absolute magnitude.
