Esli u Vas est' na kryshe gorizontal'nyi vodostok,
i u Vas est' vozmozhnost' bezopasno k nemu dobrat'sya,
Vy mozhete vzyat' kistochku i po-smetat' tverdye krupinki.
Tak eto i est' mikrometeority i ih na Zemlyu padaet
ezhegodno bol'she chem Vy sebe mozhete predstavit'.
Eto zhe ne meloch', za milliardy let
etogo laina na lune dolzhna byt' vsya
poverhnost' pokryta rovnym sloem.

Meteory nablyudayutsya v techenie vsego goda. Inogda ih nazyvayut "padayushimi zvezdami". No na samom dele rech' zdes' idet ne o zvezdah, a o mel'chaishih chasticah kosmicheskoi pyli (vesyashih men'she millionnoi doli gramma), kotoraya, padaya na Zemlyu, soedinyayas' s sostavlyayushimi Zemnoi atmosfery - ostavlyaet za soboi yarkii svetyashiisya shleif. Sgorayut meteory s atmosfere na vysote 80-120 km. Po ocenkam specialistov, v techenie goda Zemlya zahvatyvaet bol'she 200 mln. kg meteornogo veshestva. Desyataya chast' etoi massy dostigaet poverhnosti v forme meteoritov i mikrometeoritov.
