B. the distance the star is from Earth
Explicação
## Step 1
The absolute magnitude of a star is a measure of the amount of light that would be received from the star if it were placed at a standard distance of 10 parsecs (32.6 light years) from the observer. This is different from the apparent magnitude, which is the brightness of the star as seen from Earth.
## Step 2
The absolute magnitude is used to compare the true brightness of stars, regardless of their distance from Earth. This is because the apparent magnitude can be influenced by the distance of the star from Earth.
## Step 3
The absolute magnitude is not determined by the constellation the star is in, the number of times the star rotates, or the number of prominences the star makes. These factors do not affect the amount of light that would be received from the star if it were placed at a standard distance.
