Inclinations and semimajor axes of meteoroids of various Pf classes and near-Earth objects (asteroids and comets with perihelion distance q < 1.3 AU). Semimajor axes (a) are restricted to 0.9-5 AU. Only sporadic meteoroids (i.e., not belonging to any of the 16 major meteor showers) with masses larger than 5 g are shown. No meteoroid with a < 5 AU has inclination lager than 90°. Meteoroids with iron or Na-poor spectra are marked. See Fig. 8 for legends. The region occupied primarily by comets and cometary meteoroids is highlighted in yellow.
