gwiz665says...Uranus: "Hey Pluto, you're not a planet like us anymore, sit in the back of the bus."
Pluto: "Aw dang."
Psychologicsays...If we continued to count Pluto as a planet, along with everything else in our solar system of similar size and irregular orbit, we'd have dozens of planets by now.
zomggsays...I love this man too!
14468says...Tyson is wrong about Pluto. It is a planet because unlike most objects in the Kuiper Belt, it is large enough to have pulled itself into a round shape--a condition known as hydrostatic equilibrium. When this happens, objects become geologically differentiated, just like the larger planets and unlike shapeless, inert asteroids and KBOs. An object in hydrostatic equilibrium orbiting a star (and not a star itself) is a planet. If that means we have dozens of planets, then so be it. The universe was not designed for our convenience.
GeeSussFreeKsays...That is a really cleaver solution for object movement...just have to see it way far out which is where the real problem is still.
