Full Orbit from Above
Heliocentric orbit (ECLIPJ2000) of
1I/‘Oumuamua, 2I/Borisov, 3I/ATLAS, Earth, Mars,
and Jupiter. Larger markers denote discovery positions;
smaller markers ISO-planet closest approaches. Vernal
equinox is indicated, arrows point to the motion direction,
and below-ecliptic ISO’s trajectories are shown in gray.
