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.
