Improved physical properties database of trans-Neptunian dwarf planets

Abstract

Because of the objectively existing causes, such as an irregular shape of a celestial body, the lack of the satellites, the low values of albedo at moderate sizes, and a large remoteness from the Sun, creating a more exact the physical properties database of trans-Neptunian dwarf planets in comparison with existing that continues to remain a problem. We offer a new calculation procedure of the physical properties of these objects involving earlier unknown the relationships harmonizing these properties. It allows us to conjecture of they are a group of uniform celestial bodies by their origin beyond the Kuiper belt. The calculated physical properties of these dwarf planets are in a good agreement with the estimates received from observational data and can form the basis for support the validity of this improved physical properties database.
