Abstract

The probable role of comets in formation prebiotic conditions on the Earth and Mars is analyzed. The exclusiveness of the Earth position in a solar System is considered from the point of view of interaction with comets and cometary head. As the intensive excretion begins with a surface of comets begins on a distance, comparable with spacing interval from the Earth up to the Sun, quantity of cometary gas and dust able to fall on the Earth and Mars can differ more than on the order. In particular, it concerns to substances accepting active participation in formation prebiotic conditions and synthesis of prebiological compounds (HCN, CH₃OH, H₂CO, CS, H₂S, HNC, CO). On an example of a Hole-Bopp comet in the work is made the comparison of quantity of a cometary's matter, which would drop out on a surface of the Earth and Mars in case of transiting a similar comet near to planets. It means that in case of influence of cometary's matter to forming prebiotic conditions on terrestrial planets, this influence for the Earth is much more, than for Mars.
