Stars

Stars Stars Magnitudes The magnitude scale was invented by an ancient Greek astronomer named Hipparchus in about 150 BC He arrange the stars he could see in terms of their giftedness, with 1 representing the silvernest checkmate to 6 representing the faintest. Modern astronomy has extended this system to stars brighter than Hipparchus offshoot magnitude stars and ones much, much fainter than 6. As it turns out, the eye senses brightness logarithmically, so each increase in 5 magnitudes corresponds to a dropping off in brightness by a instrument 100.

The rank(a) magnitude is the magnitude the stars would have if viewed from a distance of 10 pa rsecs or some 32.6 light years. Obviously, Deneb is intrinsically very bright to make this list from its greater distance. Rigel, of nearly the same exacting magnitude, but closer, stands even higher in the list. Note that more or less of these distances be really nearby, on a cosmic scale, and that they be generally uncertain by at least 20%.
