| Description |
Spacecrafts are using to study the primordial matter of cometary nuclei. But there are about 15 meteor streams associated with comet nuclei and asteroids. Meteorites found on the surface of the Earth have crust formed under high temperature. This crust is a good thermal insulator, so that persist even for minerals that can not withstand high heat. Therefore, we propose that for the study of the nature of cometary nuclei and the substance with initial chemical composition in the Earth's environment, you need to carefully study meteorites falling on the surface of the Earth. The larger size of a meteorite, the greater chance that the temperature conditions at its entry into the Earth's atmosphere did not change the original structure and the chemical composition of the substance from which it was formed at the time of the birth of planetesimals in the Solar system. Therefore, the primary cometary material can be found on Earth, not in space a million miles from Earth.
