DETERMINATION OF PHYSICAL AND KINEMATIC PARAMETERS OF SPACE OBJECTS AND SYSTEMS USING PHOTOMETRY

Prospect of further implementation in 2021 – 2022: completed

Research level: no analogues in the world

Availability of a patent: no.

What additional actions requires further research in 2021: needs funding to implement the results.

Brief characteristics, advantages, further application perspective.

For the first time, the physical properties of the surface and the dynamic history of the asteroid (2579) Spartacus were investigated and it was found that it is in retrograde rotation and has an orbital drift direction, which corresponds to its origin from the asteroid Vesta about a million years ago. The atlas of light curves and the database of photometric measurements have been replenished with almost 3.5 thousand records of observations of satellites and large bodies of space scrap in low orbit. A new solution has been found for the axis of rotation of the inactive Ukrainian satellite Sich-2 and new data on the evolution of the rotation speed and nutation period of the Topex spacecraft rotation axis and the properties of light reflection from the satellite data. Augmented model for numerical simulation of the motion of small bodies in the solar system. For the first time in an asteroid system, five harmonics of the gravitational field were taken into account; the force of pressure of sunlight on the components of the asteroid system and the influence of resonance effects. The OMT-800 telescope made observations of 57 asteroids, 50 comets and 20 stellar and extragalactic objects. New and confirmed previously known periods of rotation for selected asteroids (asteroid systems) based on photometric observations of the OMT-800 telescope. The results of studying the movement of artificial bodies in near-earth space are used to monitor space safety. An act was received on the use of the research results by the National Center for Control and Testing of Space Vehicles.
