    #6 is true only because asteroids are defined as such. In fact, there may be more rocky/icy solar system bodies beyond Neptune in the Kuiper Belt and Oort Clouds (including Pluto!), but since they aren’t called asteroids, they don’t count.

    Some of these I knew, others I did not. Very interesting.

    Simple… right click, save as, on a flash… take it to Kinkos… think as long as you don’t try to profit from it you should be ok…

    Hmm a few new ones but really, 2,3,4 and 6 are kind of obvious, most people should know those… I can understand 14, while kind of basic/obvious it’s a lesser know fact but everyone should know sol is the biggest object in the system and that Jupiter is the largest planet…

    I’m also a bit sceptic to 5… I mean if Saturn where a solid object with it’s density and we had an ocean somewhere large enough to put it it would float, but Saturn is mainly made up of gas and I have this feeling like a big ball of gas might not behave like a solid option when you try to put it in water and that’s ignoring atmospheres and how the planet providing the ocean and Saturn would react to each other :p

    Then there is 7, a black hole could suck a smaller one in and then bellow two could collide and merge… Well that’s just what would happen if one black hole “sucked” another one in… They aren’t holes, just enormous bodies with such a weight to size ratio (density) that the gravitational field they generate won’t let even light escape (hence black and impossible to see), anything “sucked” in one should be added to it’s mass to a degree, providing it isnt small enough to be completely obliterated by the collision itself…

    Oh, huh, always figured they would be asteroids too :p had to go look it up, apparently most of the bodies in the kuiper belt and oort clouds are made up of methane, ammonia and water while the term asteroid is mostly used for rocky and or metallic bodies…

    If the earth fell into a black hole it would be smaller than a peanut.

  12. ALI meant alot to me
