Star rotates one way, it orbits around it the other way: http://www.physorg.com/news/2011-06-planet-wrong.html Pat There has been at least one recent article on Jupiter size wandering planets being not that rare. Given that premise a star could capture an additional planet that would be in retrograde. I would imagine the new planet could also be way out of plane with the rest of the system. Copernicus and Kepler on a really complicated system with multiple planes for the planets would really have a good time. Might also make for some really interesting asteroid groupings ala a three dimensional perturbation model. * * Val Kraut Sure thing about capturing and weird asteroid trajectories, though somewhat unlikely but certainly not impossible, and not that something better than 1e12 wandering/rogue items are in any short supply. Make that 1e13 if we're including everything of Ceres or larger because stars tend to poop out and lose track or whatever tidal grip of their planets. Supposedly our sun is a 3rd or 4th generation star, whereas the generation before had lost it's collection of planets. http://www.wanttoknow.info/ http://translate.google.com/# Brad Guth, Brad_Guth, Brad.Guth, BradGuth, BG / “Guth Usenet” |

Ok, Kids, today's New Word (TM) is 'retrograde'. Can Everyone say it? Let's try: Ret-ro-grade. Very good, I knew you could! Now, let's play a game. Go to Mommy & Daddy's room and mail all the pieces of paper with pictures of dead presidents to: Uncle CFL, care of your local usenet newsgroup! Dear Uncle CFL, I'm sorry, but all that my parents have are pictures of Benjamin Franklin. I learned that he wasn't a president, so I took them all out to the back yard and burned them. Aren't you proud of me? -- "Growth for the sake of growth is the ideology of the cancer cell." -- Ed Abbey |
