The area within the orbit of the Kuiper Belt object (KBO) Arrokoth (or
2014MU69) is approximated using the corresponding ellipse. The fact
that the Sun lies at a focus of the ellipse is of interest. Attention
is made to the known deviations of orbits from their models. It is at
least of interest that the ellipse model is still essentially valid.
Theoretically, if there were only the Sun and Arrokoth in the
Universe, the orbit would be precisely described by the ellipse
model.
