That's one of the fastest macroscopic solid objects with relation to its original environment. It is an entire star traveling on hyperbolic trajectory out of Milky Way. Even at the distance where we are from the center of Milky Way the escape velocity is still over 500 km/s and if I remember the number of detected objects that are on trajectory to escape our galaxy can be counted on the fingers of your hands.
