Abstract
The interaction of the Tunguska cosmic body and the Chelyabinsk object (Chebarkul meteorite) with the atmosphere has many common characteristics. The water vapor, caused by fragmentation of objects before their penetration in the atmosphere, was registered at the altitude of the mesopause in both events. The rainbow bands, which were seen in the tail of the Tunguska body, are connected with refraction and reflection of sunny rays in horizontal (parhelic) ring. A forming of explosion rejections of the substance from the Chelyabinsk object with a speed of ~ 1 km/s (which is typical for comets) and a fragmentation of the object outside the atmosphere lead to conclusion about the comet nature of the Chelyabinsk object.
