Synonyms Used in print (Frank Oppenheimer, "Science and Fear-- A Discussion...)A meteor could fall on San_Francisco . (J. F. Vedder, "Micrometeorites", in Francis S. J...)In_addition , the size distribution obtained from visual and radar observations of meteors may be extrapolated to the micrometeorite domain . However , the conversion from mass to size is unreliable , since many photographic meteors give evidence of a fluffy , loosely bound meteorite structure with densities as low as * * f . Zodiacal_light and the gegenschein give some evidence for such a dust blanket , a phenomenon also to be expected if the dust before capture is in circular orbits about the sun , as indicated by the trend of the smaller visible meteors . The flux of micrometeorites in the neighborhood of the Earth can be estimated by extrapolation from radar and visual meteor data . Related terms |
