The evolution of orbits of asteroids found in the IRAS and WISE albedo databases was calculated numerically from 2005 to 2016. It follows from the analysis of the obtained results that a certain nongravitational effect (NGE) currently affects the motion of a considerable fraction of main-belt asteroids with diameters up to 40 km. This conclusion ag...
For the study of Moon’s physical libration we need to obtain daily and annual records of the traces of stars on the celestial sphere of the satellite. Then, necessary to compare the selenographic coordinates of the stars for different models of the gravitational field of the Moon. Preliminary estimates show that the camera for observing of stars ca...

We present the results of the numerical calculations of the
orbital evolution of the main belt (MB) asteroids over the period from 2005 to 2016. We show that, at the present time, the
non-gravitational effects of a cometary nature are the essential factors affecting changes in the semi-major axes of the orbits of a significant part of the MB low-...
Observing stars from the Moon’s surface by astronomical methods will make it possible to investigate its physical libration. For its study you should get the daily and annual “tracks” of stars on celestial sphere from the surface of the Moon. For this purposes we plan to install on its surface camera for observing stars. Our estimates show that the...
To reach the Moon – is very expensive. So it makes sense to speak only about astronomical observations, which in principle can be carried out only from the Moon, and does not use significant resources. One of the important tasks, which can be solved by astronomical methods at observations of the sky from the Moon’s surface, is the study of the phys...
An approach to search for the connection of tidal forces from the Moon and the Sun with earthquakes is proposed.

If there is an influence of the Moon and Sun on occurrence of earthquakes, the physical nature of such influence can only be the gravitational. A possible gravitational influence is caused by the resultant tidal forces of those bodies, but not by their separate actions. There were calculated tidal forces of the Moon and the Sun and their resultant...
