Eccentricities 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 and eccentricities (e) to 0.4–1. All meteoroids with lower a or e are of class Pf-I, except two, which are Pf-II. Curves of constant perihelion (q) or aphelion (Q) distance are shown for selected values. Only meteoroids with masses larger than 5 g are shown. Regions where members of meteor showers Taurids (TAU), α Capricornids (CAP), Geminids (GEM), and Southern δ Aquariids (SDA) are found are highlighted (but not all meteoroids in that regions belong to the showers, and some shower members can be found also outside the regions). Meteoroids with iron or Na-poor spectra are marked. The region occupied primarily by comets and cometary meteoroids is highlighted in yellow.
