- Description:
- All known groups of fireballs contain bodies which may reach the Earths surface as meteorites and are of planetary origin. Since some fireballs have cometary orbits in the Solar System, then comets are probably of planetary origin. The possible explosion of a large planet is discussed again. This time on the basis of gravitationally decelerated expansion of an originally superdense embryo.
