Inclinations and perihelion distances of meteoroids, comets, and asteroids on excited orbits (i.e., with Q > 4.9 AU, a < 5 AU, and either e > 0.9 or i > 40°). Meteoroid Pf classes are coded by different symbols, as shown in the legend. Meteoroids with Na-poor spectra are marked. In contrast to Fig. 9, meteoroids of all masses and showers are included. The regions of Southern δ Aquariids (SDA) and Quadrantids (QUA), which overlap with November Draconids (NED), are highlighted. Near-Sun asteroids according to Emel’yanenko (2017) are included and shown by different symbols, even if they have Q < 4.9. The strong Karlštejn meteoroid observed in 1997 (Spurný & Borovička 1999b) is also included. For asteroid 2009 WN25, the orbit valid in 2018 was used.
