Orbit in Oblique View
Oblique view of the portion of Comet 2I/Borisov's orbit around perigee, viewed from 30° above the ecliptic plane.
Orbit in Earth Co-Orbital View
The orbit of Comet 2I/Borisov around perihelion, in the Earth's co-orbital reference frame, as seen from above (top panel) and in the ecliptic plane (bottom panel). The black circle denotes the comet's position at perigee (2019-Dec-28) and the open circles show positions at 30-day intervals.
