The 1000 backward-integrated orbits of DESI-HVS1 in Galactocentric cylindrical coordinates (R_GC, Z_GC), computed under three different Galactic potential models and sampled from the uncertainties in its position and velocity. The black dashed curve shows the fiducial orbit. The blue, red, and green points represent the current position, the perigalacticon, and the position after 50 Myr of backward orbital integration, respectively. The horizontal dashed line indicates the disk plane (Z_GC = 0 kpc), and the GC at (R_GC, Z_GC) = (0, 0) kpc is marked by a red cross. The orbits are ballistic and nonclosed and exhibit a pronounced turning near perigalacticon.
