QCCQ Welcome to the Solar System

Quote " Now the first thing you are likely to realize is that space is extremely well named and rather dismayingly uneventful. Our solar system may be the liveliest thing for trillions of miles, but all the visible stuff in it, the sun, the planets and their moons, the billion or so tumbling rocks of the asteroid belt, comets, and other miscellaneous drifting detritus fills less than a trillionth of the available space." Comment: This quote gave a lot of information stating opinions and facts that were unbelievably real but hard to comprehend when it is taken in just one moment. Reading this was very interesting and particularly informative to the point that I wanted to learn more about what Astronomers have discovered in the past years and how it affects what we think regarding our solar system and the amount of space that we have. It's definitely amazing how much space we have to explore in order to say that we "know" what is out there in space, but for now we may have to settle with only knowing that are 8 planets in our solar system, and who knows maybe there are more to come just like Pluto, which had been discovered just recently. Connection: I have always wondered about space and time, why there is such a mystery to it and why we always think we have it figured out but rather we just find little pieces to the bigger puzzle that keeps getting bigger and bigger. Questions: Hasn't Pluto been said to not be considered a Planet anymore? Will we ever know the accuracy of the space there is in space? Are there really other living things in other planets other than Earth? Why did Lowell get all the credit for the finding of Pluto, if Tombaugh finished his research when Lowell had died, he should have taken some credit right?
