WHAT IS APPARENT MAGNITUDE?

Categories of star glow
Astronomy today defines two types of magnitude. Apparent magnitude and absolute magnitude. In the text that follows, I’m telling you about the apparent magnitude. Looking at the starry sky, you notice that the stars shine with a different glow. Some are dominantly bright and some are barely visible. In the time before the telescope appeared, people relied on their star observations for what they saw with their eyes. They divided the star into six categories. Even then, we can say, at six different brightnesses of stars. Twenty brightest stars were declared as 1 category, and stars were rated up to 6 stars as the least visible. The smaller the number, the brighter the star. A person with good vision, in a dark place and under clear skies, can see the glow of stars up to sixth size. In the 18th century, astronomers found that a 6 magnitude star was 100 times darker than a 1 size star. By this logic, they concluded that the star of the first magnitude was 2,512 times brighter than the star of the second magnitude. Pure logarithmic scale. When telescopes appeared, astronomers realized that there were billions of other stars they had never seen before. They realized that there were higher magnitudes because they saw stars of even lower gloss than sixth magnitude.
Apparent magnitude
Let’s repeat. The weaker the star, the greater its magnitude. At that time, the brightness scale of the stars was made, from the brightest to the least visible. When they look
