The results out-of pc simulations show that more 1% of one’s bodies is reach the orbit out of Planet from the region of Uranus and you may Neptune [cuatro,5]. New obtained efficiency reveal that the common day as much as the fresh collision which have World is equivalent to ten^8 many years (but due to the ejection of the Jupiter the brand new lifetime of such stuff may be ten minutes reduced). The typical go out when some object having an excellent diameter d > D affects Planet may be comparable to 0. I have made a few calculations of developing discs initial composed of planets and Mars-crossing stuff.
The latest size shipment from Environment-crossing items e because you to into the fundamental asteroid belt
In certain runs items plus have been Earth- and you will Jupiter-crossers. The latest gravitational dictate off worlds are taken into account because of the action spheres means, i. We discovered that some items moved in order to Jupiter, and that thrown her or him into the hyperbolic orbits, and lots of items moved into the space. In the initial eccentricities elizabeth(sub)o = 0. Over step one% of all first items influenced World during advancement. Just how many stuff one affected Venus and you may Mercury wasn’t a lot less than one to to have Earth. Within past amounts away from computer advancement, specific things were just Mercury- and Venus-crossers. In the elizabeth(sub)o = 0. If the initially items crossed just the orbit of Mars, then means of migration is slowly and items affected Mars than Planet. References: Ipatov S.
