Projection of the orbit of 311P/PanSTARRS on the x–y plane, x–z plane, and y–z plane of the ecliptic coordinate system ECLIPJ2000. The outer cyan line corresponds to the orbit of 311P, and the inner one corresponds to the orbit of the Earth. The symbol ⋆ in the center represents the Sun. Cyan and red dots on different orbits represent the positions of 311P and the Earth at different observation epochs (2013 September 10, 2013 September 23, 2013 October 18, 2013 November 13, 2013 December 8, 2013 December 31, and 2014 February 11). The orbital simulation of 311P is performed with the N-body integrator REBOUND (Rein & Liu 2011).
