The orbits of Milky Way satellite galaxies over the last 3 billion years. Circular symbols indicate where satellites are located today, while curves represent the backwards trajectories of satellite galaxies. The dark matter halo of the Milky Way is approximated by the gray sphere. Orbits of the Large and Small Magellanic Clouds are indicated with solid and dashed black lines, respectively.  The group of ultra-faint satellite galaxies identified to be companions of the Magellanic Clouds in Patel+20 (Carina 2, Carina 3, Horologium 1, Hydrus 1, Phoenix 2, and Reticulum 2) are in blue. These satellites clearly evidence a shared orbital history with the Clouds over the last 3 billion years and have entered the dark matter halo of the Milky Way as a group, providing the first confirmation of a group accretion scenario.
