Initial distances from the Sun for planetesimals that collided with forming terrestrial planets and the Moon
Abstract
The embryos of the terrestrial planets with masses about 0.1 of masses of the planets accumulated mainly material from their neighbourhoods. The amount of material from different parts of the zone from 0.7 to 1.5 AU from the Sun, which collided with almost formed the Earth and Venus, differed for these planets, probably, by no more than 2 times. Inner layers of each terrestrial planet could be accumulated mainly from planetesimals from the neighbourhood of this planet. The outer layers of the Earth and Venus could accumulate similar planetesimals from the feeding zone of the terrestrial planets.
