Stars Mike McCann Science Report Science Report P.d. 4 STARS The magnitude scale was invented by an ancient Greek stargazer named Hipparchus in roughly 150 BC He distinguish the stars he could see in terms of their sheenyness, with 1 representing the blindingest small-scale to 6 representing the faintest. Modern astronomy has extended this system to stars brighter than Hipparchus foremost 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 overtake in brightness by a factor 100.
The implicit magnitude is the magnitude the stars would have if viewed from a distance of 10 parsecs 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 absolute magnitude, but closer, stands even higher in the list. Note that about of these distances are really nearby, on a cosmic scale, a...If you emergency to get a full essay, order it on our website:
