Fig. 4


Distributions of elements of the modeled particle orbits approaching Earth’s orbit at a distance shorter than 0.05 AU at present. Specifically, relative distributions, in arbitrary units, of the perihelion distance a), semi-major axis b); eccentricity c); argument of perihelion d); longitude of ascending node e); and inclination to the ecliptic f) are shown for nine streams modeled for nine times before the present. The times are indicated at the right top corner of plot b). For clarity, the distribution for each successive time is shifted up relatively to the distribution for the preceding time and only two thirds of the peak in the distribution of the longitude of the ascending node and inclination (e) and f)) for model M500 are shown in the chosen vertical scale.
