 Studies say that a triple-star system was traveling through the center of the Milky Way when it came too close to the galactic center (which is thought to have a giant black hole).One of the stars was captured by the black hole causing the other two to be ejected from the Milky Way, where they merged to form a hot blue star.The star is moving at a speed of , about three times faster than the Sun's orbital velocity around the galaxy's center, and also faster than the galaxy's escape velocity.
