A 3D animation showing the orbits of 18 galaxies (5 classical dwarfs + 13 ultra-faint satellites) in the Milky Way's Vast Polar Structure (VPOS) over the last 3.5 Gyr. Magellanic satellites are illustrated in pink and are seen falling into the halo of the MW on the bottom right. Classical satellites not in the VPOS are denoted with thick gray lines. Orbits are shown for a low mass Milky Way (MW1) and an intermediate-mass LMC (LMC2). See paper for full details.
