Web2P/Encke orbits the sun every 1,200 days (3.29 years), coming as close as 0.34 AU and reaching as far as 4.09 AU from the sun. Its orbit is highly elliptical. 2P/Encke is about 4.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay. The rotation of 2P/Encke has been observed. WebBiography. Johann Franz Encke's father was Johann Michael Encke (1749-1795), a Lutheran clergyman at the Jacobikirche (St James church) in Hamburg. His grandfather, Georg Friedrich Encke, had also been a pastor, in Altluneberg, near Bremen. His mother Marie Misler (1755-1811), was the daughter of Johann Gottfried Misler, a civil servant, …
WebA small fraction have T > 3 and these cannot cross the orbit of Jupiter. In this case, Encke-type comets have orbits interior to Jupiter's and Chiron-type comets have orbits exterior to Jupiter's. The nearly isotropic comets ( T < 2) include the HTCs and the LPCs. The latter are nearly isotropic.
WebCowell’s method seems markedly worse than Encke’s method in accuracy and speed, but is much simpler to program.

The advantage of Cowell's method is ease of application and programming. A disadvantage is that when perturbations become large in magnitude (as when an object makes a close approach to another) the errors of the method also become large. See more In astronomy, perturbation is the complex motion of a massive body subjected to forces other than the gravitational attraction of a single other massive body. The other forces can include a third (fourth, fifth, etc.) body, See more General perturbations In methods of general perturbations, general differential equations, either of motion or of change in the orbital elements, are solved analytically, usually by series expansions.

This is performed by first modeling the orbit as a Keplerian orbit. Then perturbations are added to the model to account for the various perturbations that affect the orbit. Special perturbations can be applied to any problem in celestial mechanics, as it is not limited to cases where the perturbing forces are small.
