written by Stellanaut on Nov 11, 2003 01:46 Why was it in the news in the first place? oatmeal, are you crazy? written by Raptorjedi on Nov 11, 2003 01:47 Because some people thought it was a planet, but its not... written by Overtilt on Nov 11, 2003 02:02 is that Quackquack thing the famous planet X we learned about many years ago? I remember hearing something or other about a planet X when I was a kid. Was that QuigleyQuack? oatmeal, are you crazy? written by Raptorjedi on Nov 11, 2003 02:08 Planet X is just something made up to explain the strange orbits of Neptune and Pluto.... written by Overtilt on Nov 11, 2003 02:09 Aha. Good to know that. Now I can finally breathe free. *breathes free* written by Stellanaut on Nov 11, 2003 02:10 The theory i think is correct is that pluto was captured from interstellar space. written by Overtilt on Nov 11, 2003 02:12 What are you talking about?! Pluto is just a regular dog! Nothing extra-terrestial about him. oatmeal, are you crazy? written by Raptorjedi on Nov 11, 2003 02:13 It probably was, but we werent there, so we dont know, the thing that always makes me wonder is why they still call Charon a moon, and not a planet.... technically there are 10, because Pluto/Charon is a double planet, but since it was called a moon first, its stuck.... hang in there written by Lightning4 on Nov 11, 2003 03:21 Well technically Charon would prbobably be called a moon, as Charon is smaller than Pluto.. not by much. electronic engineer! written by Leniad on Nov 11, 2003 03:26 Isn't Charon orbiting Pluto? Then it's a moon. Planets are supposed to orbit around their star... journeyman written by Stargazer on Nov 11, 2003 07:26 Leniad said: Isn't Charon orbiting Pluto? Then it's a moon. The center of mass and gravity between the two objects are between Pluto and Charon - so they are technically a double-planet; not quite a moon-planet system as Earth-Luna - where the center of mass is within Earth itself as it's so much larger then the moon; this is not the case with Pluto and Charon. └> last changed by Stargazer on November 11, 2003 at 10:19 meep written by Naavis on Nov 11, 2003 07:32 Isn't the center of gravity of earth and the moon also between earth and the moon, except that it's more closer to earth than the moon? Center of gravity of earth and moon, that sounds odd.. EDIT: My great powers of Corel Photopaint. I'm much better with photoshop, but I'm at work and there's no photoshop here. -_- EDIT2: I think my posts don't make any sense.... └> last changed by Naavis on November 11, 2003 at 12:49 journeyman written by Stargazer on Nov 11, 2003 07:39 Naavis said: Isn't the center of gravity of earth and the moon also between earth and the moon, except that it's more closer to earth than the moon? Actually, I'm not quite sure about that; mass = gravity, after all, and as Earth has many times the mass of the moon, the center of mass and gravity between the two objects are probably very close to Earth, possibly within its amtosphere. I could solve this with some quick math, but I have to go to class soon, so I'll take a look at it later. └> last changed by Stargazer on November 11, 2003 at 10:19 written by Vib rib on Nov 11, 2003 07:51 Mass does not equal gravity. Nor are they, by necessity, directly proportional in themselves. journeyman written by Stargazer on Nov 11, 2003 08:51 Vib rib said: Mass does not equal gravity. Nor are they, by necessity, directly proportional in themselves. The grater the mass, the more it attracts, Vib. So, as Einstein said, we may have to assume some relationship between them.
