Distribution of the cloud of 16 545 clones of P0230 stopped at the closest proximity to the Sun about 2.80 Myr ago. All points are projected onto the maximum scatter plane X′ Y′. The green dot marks the nominal approach position, while the red one depicts the position of the Sun. The blue circle shows the widely adopted approximate boundary of the Oort cometary cloud at 0.5 pc from the Sun. Orange dot and arrows showthe position of C/2015 XY1 at the moment of the nominal P0230 approach; see Sect. 5 for details.
