NASA has as much chance of breaking Temple1 up with the planned experiment as I have with a slug gun! The radiation (in our case) from the Sun causes cometary 'tails' and jets of matter that, in them selves, can slightly change the orbit of this sort of body. Perhaps your Russian astrologer nutter should sue the Sun for having such an effect upon all orbiting bodies.... |

Mars and jupiter play catch with it. But 1000 kilometers a year difference is going to put an end to it. The whole point of a stable resonance is that any small perturbation such as is produced by outgassing tends to change the distance at the next close encounter to the planets in a way that causes a correction to the motion to restore the object towards the original path. Otherwise it would have drifted out of the pattern long ago. Since the delta_V from the impactor will be less than the cumulative effect of outgassing, there is no risk of changing its orbit permanently.

Ellis, temple1 doesn't approach the sun. Mars and jupiter play catch with it. But 1000 kilometers a year difference is going to put an end to it. I *knew* you'd leap to the wrong conclusion, but I was hoping that you would pleasantly surprise me... Here's some history on Comet Tempel 1: The comet was very well placed for its 1867 discovery thanks to its closest approach to Earth (0.568 AU) and its perihelion (1.562 AU), which occurred on May 15 and May 24, respectively. Over the next five months after its initial detection, subsequent observations were frequently made. The comet was last detected on August 27, 1867 by Julius Schmidt, at which point the comet had become too faint for position measurements. At that time the comet was 1.30 AU from Earth and 1.81 AU from the sun. The comet was first recognized as periodic in May of 1867 when C. Bruhns of Leipzig determined the orbital period to be 5.74 years. By the time the final observations had been made of the 1867 apparition, the orbital period had been re-calculated to be 5.68 years. The comet was recovered on April 4, 1873 by E.J.M. Stephan of Marseilles, France. The comet remained under observation until July 1st of that year. Predictions were made for an 1879 return, with the most ambitious being that of Raoul Gautier who computed definitive orbits from the two previous appearances before making his predictions for the upcoming return. Gautier's predictions enabled Tempel to recover the comet on April 25, 1879. The comet was observed until its last detection on July 8. In 1881, comet Tempel 1 passed 0.55 AU from Jupiter. Due to gravitational interactions, the comet's orbital period was increased to 6.5 years and the perihelion distance was increased from 1.8 AU to 2.1 AU, making the comet an even fainter object. Subsequently, the comet was lost and it was not observed at its next expected return. Photographic attempts during 1898 and 1905 failed to recover the comet. During 1963, B.G. Marsden conducted an investigation as to why comet Tempel 1 became lost. He found that further close approaches to Jupiter in 1941 (0.41 AU) and 1953 (0.77 AU) had decreased both the perihelion distance and the orbital period to values smaller than when the comet was initially discovered. These approaches moved Tempel 1 into its present libration around the 1:2 resonance with Jupiter. Subsequently, Marsden published predictions for the 1967 and 1972 returns in his paper On the Orbits of Some Long Lost Comets. (Courtesy of NASA Astrophysics Data System, from the website http://deepimpact.jpl.nasa.gov/science/tempel1.html) Jupiter has a much greater effect on its orbit than anything that the Deep Impact impactor could possibly do. Will you finally accept this fact? Temple one isn't going to be a anomaly any more it's now back to space debris for it. condemned by NASA. Why do you keep referring to it as an "anomaly"? Do you think that there will never ever be another comet in the same situation as Tempel 1? -- Jim Phillips, jay pee aitch eye el el eye pee at bee see pee ell dot net "Moms and dads these days are like the Democratic party: lame, spineless and not holding up their end of the equation.
