Does comet ISON have a 333 year orbit? | |
green_girl User ID: 49871189 Canada 11/17/2013 07:12 PM Report Abusive Post Report Copyright Violation | Perhaps you missed the part where I integrated the orbit for 1 million years and it's STILL hyperbolic. Simple questions: How much energy is needed to change hyperbolic to parabolic in this case (do we know the ISON mass to calculate this)? Let's say in 1920s ISON traveled 4km/s so something as small as the Earth can change ISON direction 180degrees ( U-turn ) 113 AU from the Sun, do we know what is there. Do we know all energies possible (not only gravity) during close miss ISON-Sun to be sure what will happen. Be cool, use discernment, be Yourself. so are you asking if ison will ever decide to turn around and come back? I would say the answer is no. It is going to leave the solar system, that is determined to be the only thing it can do based on the speed and trajectory. As it moves out it will begin to lose momentum. When it loses enough momentum it can begin to be effected by bodies that exert enough force, but there are not a lot of bodies outside of our solar system for a long long while. And even if it does meet something out there, there is not much chance that it will be turned back towards us. it would get a brand new path leading it somewhere else. But astro's models would include other bodies too, so if he says it is not coming back, i am doubly certain of my response. :malefav: I love this place!! |

Quoting: Anonymous Coward 49479441 the orbit of Ison and this comet are so similar, but they say it's broke into two. 2 comets, with a 333 year orbit. do the math. Neither one has a 333 year orbit. ISON is hyperbolic and C/1680 V1's orbit lasts about 10,000 years, not 333. |

So you're suggesting that it's going to free return around an impossibly large undiscovered planet at too close a distance to the sun ( [link to arxiv.org] ) and magically return to the sun on the same path every 333 years? No that is not how things work in real life. |

Quoting: Anonymous Coward 45198861 It doesn't make this trip every 333 years, as I reveal in the video. It's a hyperbolic comet. correct, it is a 313 year orbit :killshot313: |
Dr. Astro (OP) Senior Forum Moderator User ID: 48376296 United States 11/17/2013 08:12 PM Report Abusive Post Report Copyright Violation | 166.5 years from now (333 / 2) ISON a.d.1846 171AU from the Sun, 3.2 km/s Detectability 150 - 200 au (m_Mars), Mars escape speed 5km/s You said earth, now you're saying Mars. While either one could perturb the comet, it would have to be deliberately placed at just the right spot to produce a return trajectory. My claim is not "same comet every 333 years", Quoting: dotmy claim is "impossible because never happen before" is not true. Now you're just trolling. |

Quoting: Anonymous Coward 49830588 Is what Thor is talking about in his latest thread correct? An unprecedented event with 1000's of incoming comets? link pls? [link to www.godlikeproductions.com] that is the link. No there is nothing in it to imply the claims are true. no thousand comets incoming. aside from the ones we always knew were coming. :malefav: I love this place!! |

Hey troll: [link to img6.imageshack.us] Horizons will only go out a few hundred years, but it clearly shows that ISON's long term eccentricity is hyperbolic. It only drops below one for a brief while before it is ejected from the solar system. I used that drop to my advantage to get ISON to display in Celestia since Celestia only knows how to work with comets with an eccentricity less than 1; I used the osculating elements from this period so that it would display the comet. This is neither a surprise nor an "incorrect prediction." |
