Top panel: cumulative distribution of the original orbital energy for the observable new comets obtained from the simulations (green line), for the JPLWC sample (gray line), and for the WC sample (black line). For the simulations, the color width is proportional to the numbers of comets in each class. Red, blue, orange, and magenta correspond to the jumpers, creepers, KQ-jumpers, and KQ-creepers, respectively. Middle panel: number of comets per bin of constant orbital energy width normalized to the total number of comets for each sample. Each been is colored according to the proportion of comets in each class. Bottom panel: proportion of retrograde orbits for a semi-major axis smaller than 25 000 AU and a semi-major axis greater than 25 000 AU. The color-coding for the middle and bottom panel is the same as for the top panel.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
