Rolan Kiladze mainly studied the matters of origins and movement of solar system bodies. He developed the universal formula, which makes possible to calculate the length of day period for the distant planets. This theory is based on the fact that every planet started its spinning motion yet being in an earliest stage of formation, under the influence of strong impacts of particles moving in the opposite direction (1965).
Based on the theory of planetary genesis, developed by Rolan Kiladze, it is possible to determine planetary speeds of spinning motions, masses, diameters and distances from the sun;
He determined mass of planet Pluto (1966).
In the result of observations on transit of sun by planet Mercury, Rolan Kiladze managed to establish the signs of existencew of atmosphere on Mercury (1974).
With the employment of photometric method, he calculated the widths of Saturn’s rings (1967). This results were approved by French scientists in 1981 and by observations held by means of teh Hubble Space telescope in 1995.
In 1975 he discovered supernova in Cygnus constellation.
Rolan Kiladze as early as in 1976 suggested that planet Pluto is still in the formation stage, that there is cloud of particles around Pluto. Also, Kiladze predicted the existence of Pluto’s satellite Charon one year prior to its discovery.
In 1986 he developed theory for modern rotation of planets. The discovery of Pluto’s two small satellites in 2005 may be accepted as the proof of this theory.
In cooperation with his colleagues from St. Petersburg, Kiladze developed the theory of geostationary satellites’ movement (2001). While working on the theory or movement of ‘resonant satellites’ he discovered sixth ‘First Integral’, the essence of which is that orientation of satellite is related to the position of Moon. This discovery is formed in the shape of mathematical formula. The computer programs built based on this theory make possible to determine coordinates of all existing geostationary satellites’ for several decades ahead, and so improve the elements of their orbits. He established that carrier rockets of geostationary satellites occasionally explode, and discovered phenomenon of regularization of their debris’ orbits (2003). Hence, based on this discovery, the theoretical possibility of collection of space debris was designed.
Rolan Kiladze found the criterion of prediction (on the basis of only two positional observations held in short period) for asteroid’s collision with Earth in 2004.
Rolan Kiladze is the co-author of: monographs, manuals for high-school students, three improved catalogues of unguided geostationary satellites, and more than 150 scientific articles; Editor and advisor of several popular science books.
