Naos is the nearest class O star to the Sun and one of the most luminous stars visible to the unaided eye. · Annie Jump Cannon; Pickering and the Harvard Computers – 1913; Annie Jump Cannon developed the Harvard system to fulfill the need for a robust yet straightforward classification scheme. The largest part of its lifetime is spent as a main sequence star during which hydrogen is being converted to helium balancing gravitational contraction so that the radius and energy output remain almost constant.
Kudos. Oh, boy! Adam feels good killing mom. Stars in the B class are slightly cooler, lying somewhere between 9,750 and 31,000 degrees Kelvin.
