4179 Toutatis的轨道演化

Orbital Evolution of 4179 Toutatis

Suryadi Siregar, Endang Soegiartini

摘要:

小行星1934 CT 1989 AC,也被称为4179 Toutatis,是一颗阿波罗和火星交叉的小行星,其轨道混乱,与木星的共振比为3:1,与地球的共振比为1:4,并且经常接近地球。它被列为潜在危险物体(PHA)。这项研究的目的是调查4179 Toutatis被逐出太阳系的可能性。本文给出了4179 Toutatis在~300 kyr时间间隔内的轨道演化。利用水星子程序包,考虑了太阳系八大行星的引力摄动,对它的轨道演化进行了研究。在相对于太阳系寿命(~10 Gyr)的非常短的时间尺度(~300 kyr)内,小行星4179 Toutatis给出了一个混乱运动的例子,可以导致小行星向外移动,并可能随后逃离太阳系。

英文摘要:

Asteroid 1934 CT;1989 AC, well known as 4179 Toutatis, is an Apollo and Mars-crosser asteroid with a chaotic orbit produced by a 3:1 resonance with Jupiter and a 1:4 resonance with the Earth, and frequent close approaches to the Earth. It is listed as a potential hazardous object (PHA). The aim of this study is to investigate the possibility of 4179 Toutatis to be ejected from the Solar System. This paper presents an orbital evolution of 4179 Toutatis in time interval of ~300 kyr. Investigation of its orbital evolution is conducted by using the Mercury subroutine package, where the gravitational perturbations of eight major planets in the Solar System are considered. Over very short time scales (~300 kyr) relative to the Solar System life time (~10 Gyr), the asteroid 4179 Toutatis gave an example of chaotic motion that can cause asteroid to move outward and may be followed by escaping from the Solar System.
