"Lowelrs other abiding conviction was that there existed, somewhere
out beyond Neptune, an undiscovered ninth planet, dubbed Planet X Lowell
based this belief on irregularities he detected in the orbits of Uranus
and Neptune, and de,voted the last years of his life to trying to find the
gassy giant he was certain was out there."
I like this comment because it shows an actual person, and their dedication to something as well as their curiosity. You probably have to be very curious and ambitious to suspect that there is a ninth planet, planet x, and to actual spend the rest of your life looking for that plant until you die, thats a big sign of dedication. He was really after finding that planet, and he didn't give up.
Is planet X one of those gigantic planets that we saw in the video on the first week of this class? I remember it went past pluto or something the sun maybe, and the planets or starts, whatever they were, were just getting so big. Bigger than you can imagine.
