Assessing the meteoroid risk in near earth space

Andrey K. Murtazov
Published Online: 2018-07-05 | DOI: https://doi.org/10.1515/astro-2018-0025


The meteoroid risk in circumterrestrial space is basically caused by 1-10 mm meteoroid bodies. Meteoroid particles of such dimensions cannot be registered by modern monitoring astronomical instruments. Observable are only meteor phenomena they cause. This work analyses the activity of main meteor showers over several years and assesses the danger from meteoroids with a size of more than 1 mm. The results of calculating the meteoroid risk during these showers’ maximum activity periods have shown that despite its low values it is sufficiently close to the maximum allowable risk. This already constitutes a recognizable danger, and such a danger needs to be taken into consideration.

Keywords : circumterrestrial space; meteoroids; risk
