pluto - put in perspective
there seems to be a lot of people that somehow 'overvalue' pluto as a planet and have asked me what i think about its 'demotion. i have always thought that it should never have been called one in the first place. we, as humans, attach starnge affections to members of our solar system, where in fact the only other world visited by man is the moon.
perhaps this celestial scale puts everything in perspective best.
arcturus shines over 100 times as brightly and releases approximately 215 times more radiation than does our sun, which is an astronomical commoner, a yellow dwarf. so we, in our present state could not survive if arcturus replaced the sun in our sky.
