so far from our own Sun that it's not even
the brightest star in the sky. It is a remarkable thought that that distant
tiny twinlde has enough gravity to hold all these comets in orbit It's not
a very strong bond, so the comets drift in a stately manner, moving at
only about 220 miles an hour. From time to time some of these lonely
comets are nudged out of their nonnal orbit by some slight gravitational
perturbation-a passing star perhaps. Sometimes tlley are ejected into the
emptiness of spacel never to be seen again, but sometimes they all into
a long orbit around the Sun. About three or four of these a year, lmown
as long-period comets, pass through the inner solar system. Just occasionally
these stray visitors smack into something solid, like Bartll. That's
why we've come out here now-because the comet we have come to see
has just begun a long fall toward the center of the solar system. It is
headed fori of all places, Manson, Iowa It is going to talce a long time to
get there-three or four million years at least-50 we'll leave it for now,
and return to it much later in the story."
I find it interesting that so much is going on outside our planet and outside of our solor system and we can't even see it. It's insane to think that meteors could be coming straight for us at like 1029381902830123891092830918290381 miles an hour and we wouldnt even know about it. Even the people that do know about it, disregard it as a problem because either it's too far away or it's too unlikely to happen. I know if i knew something was coming for earth i would be really worried about it. Its also facinating how small we as a human race are. like in compairson of human to earth, we are like nothing. In compairison of earth to sun the earth is like nothing. in comparrison of the sun to the milky way the sun is like nothing. in compairson of the milky way to probably some other neighboring galaxy, the milky way is like nothing. It's so facinating to think that the universe is so big and how we are litterally nothing, not a thing that we could ever do will impact anything other than our spec of a society. We are basically not even part of the big picture. its scary almost.
