The Motions of ~14.000 Observed Stars During the Past 250 Million Years

Stars studied during a 15-year monitoring programme making their most recent orbital revolution around the Galactic centre before converging into the small volume where they were observed by the team. The duration of the video corresponds to about 250 million years. The yellow dot and white curve show how the Sun moved during this last of its about 20 laps around our Galaxy.
