Answer:
Hipparchus was an ancient Greek who classified stars based on the brightness in 129 B.C. He grouped the brightest stars and ranked them 1 (first magnitude) and dimmest stars as 6 (sixth magnitude). Thus, the smaller numbers indicated brighter stars. Now, the scale extends in negative axis as well. More the negative number, brighter is the star. For example, Sun has magnitude -26.74.
This the apparent magnitude which means the classification is based on the brightness of the star as it appears from the Earth.
The origin and magnitude of stars.
The brightness of the star is defined by the apparent magnitude and how bright it appears from the earth. The distance of 32.6 light-years affects the way the stars shine. Hipparchus in ancient Greek classified stars based on the brightness in the 129 B.C.
Thus the answer of apparent magnitude is based on the classification of how it appears from the earth.
- The brightest stars were grouped in based on their ranks as first magnitude and dimmest stars of 6 of the sixth magnitude. Thus, the smaller numbers tell a brighter star.
- Now, the scale extends in the negative axis as well. More the negative numbers have a brighter start. For example, the Sun has a magnitude of -26.74. But is the brightest.
