He developed a universal formula for determining the length of the day-night time for distant planets (1965).

Rolan Kiladze calculated the thickness of the rings of the planet Saturn (1969), which was confirmed in 1995 by the observations of the Hubble Space Telescope.

Roland Kiladze suggested that Pluto was still undergoing the process of formation and was still surrounded by particles.

Rolan Kiladze developed a theory about the modern rotations of the planets which was confirmed in 2005 by the discovery of two more moons of Pluto (1986).

Rolan Kiladze with colleagues from St. Petersburg worked out the theory of movement of geosynchronous satellites (2001).

Rolan Kiladze found the criterion for predicting an asteroid collision with Earth based on only two positional observations (2004).

R. I. Kiladze is the author of the monograph “Modern Rotation of Planets, as a Result of Development of Small Particles” (1986), “Theory of Movement of Geostationary Satellites” (2008) and the textbook for students “Theoretical Astrophysics.” He is the author of three catalogues for geostationary satellites and more than 150 scientific articles.
