Orbit of 2021 JV

oblique view of orbit

Oblique view showing the positions of the asteroid and Earth (coinciding) on the date of closest approach. The thin lines show the projection of the asteroid's orbit projected onto the ecliptic plane, with tic marks denoting 15-day intervals.

 

co-rotating orbit plot

View of the orbit in a reference frame co-rotating with the Earth. Circles denote positions of the asteroid at intervals of 30 days relative to perihelion (filled circle). The upper plot shows the view from above the ecliptic plane and the low plot is the view along the ecliptic plane.
