Estimation of the non-gravitational effects on the Centaurs orbits evolution

N. Kovalenko, Ph.D.
Astronomical Observatory of Taras Shevchenko National University of Kyiv

In this work the orbital evolution of some active Centaurs is considered for one thousand years with and without nongravitational accelerations. An impact assessment of nongravitational effects on Centaurs’ orbits is made. It is shown that a shift in the date of perihelion passage for Centaurs population objects under consideration ranges from 1 second to 79 seconds for one orbit period and from 1 sec to 0.72 days for the entire period of integration (a thousand years).
