2021 CC40 - cometary origin ?

Its orbit has a Jupiter moid = 0.0060 AU

I generated 100 clones of 2021 CC40 in the last 10^8 days (i.e. from now back to about 280K years ago).
75 clones came into the solar system from a distance greater than 100 AU

From this point of view, it seems that 2021 CC40 is a good candidate for having a cometary origin.

In the following plots, time is displayed on the vertical axis in order to have more space. The simulation time has been divided into 50 slots and for every slot the relevant orbital parameter distribution (inter-quartile) of all existing clones is shown.
