RT Journal Article SR Electronic A1 Madáč, Kamil A1 Madáč, Andrej T1 Orbital Radii and Rotation of Celestial Bodies JF Acta Mechanica Slovaca YR 2013 VO 17 IS 4 SP 48 OP 51 DO 10.21496/ams.2013.045 UL https://www.actamechanica.sk/artkey/ams-201304-0006.php 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.
