Mars - an escaping planet? | | Rudolf Dvorak

Numerical experiments with a modified Solar System consisting of a more massive Earth have shown, that for special values of an enlargement factor K around 5 the dynamical state of a truncated planetary system (excluding Mercury and the outer planets Uranus and Neptune) is highly chaotic. On the contrary for values of the mass of the Earth up to the mass of Saturn no irregular dynamical behaviour was observed. We extended our investigations to the complete planetary system and showed, that this chaotic window found before still exists. Tests in different ’Solar Systems’ showed that only including Jupiter and Saturn with their actual masses together with a ’massive’ Earth (between 4 and 6 times more massive) destabilize the orbit of Mars so that even escapes from the system are possible. | | Source: | arXiv, physics/0508142 | | Services: | Forum | Review | PDF | Favorites | |
