PT - JOURNAL ARTICLE AU - Madáč, Kamil AU - Madáč, Andrej TI - Orbital Radii and Rotation of Celestial Bodies DP - 2013 Oct 31 TA - Acta Mechanica Slovaca PG - 48--51 VI - 17 IP - 4 AID - 10.21496/ams.2013.045 IS - 13352393 AB - Orbital radii of the planets and moons are considered to be random. The predominant view says that planets and moons can orbit at any radius, similarly to satellites which can be placed at various orbits if only their orbital speed is correct one. Defining of orbital radii of the Sun's planets on their physical nature basis is unknown. The article aims to contribute to the knowledge and reasons of celestial bodies' orbital radii and about the reason of their rotation.
