RADIO PHYSICS AND RADIO ASTRONOMY

PACS numbers: 93., 96.30.Ys 

Purpose: Evaluation and analysis of distribution of the number of meteoroid (mini asteroid) falls as a function of glow energy, velocity, the region of maximum glow altitude, and geographic coordinates.

Design/methodology/approach: The satellite database on the glow of 693 mini asteroids, which were decelerated in the terrestrial atmosphere, has been used for evaluating basic meteoroid statistics.

Findings: A rapid decrease in the number of asteroids with increasing of their glow energy is confirmed. The average speed of the celestial bodies is equal to about 17.9 km/s. The altitude of maximum glow most often equals to 30–40 km. The distribution law for a number of meteoroids entering the terrestrial atmosphere in longitude and latitude (after excluding the component in latitudinal dependence due to the geometry) is approximately uniform.

Conclusions: Using a large enough database of measurements, the meteoroid (mini asteroid) statistics has been evaluated.

Key words: bolides, meter-size asteroid, mini asteroid velocity, altitude of maximum glow, statistics distributions
