How did it get moving so fast? The explanation likely includes a stellar ménage a trois gone horribly wrong some 100 million years ago. A three-star system likely wandered too close to the center of the galaxy and lost one of its members to the black hole that resides there. The momentum of the captured star – and keep in mind, near the center of the galaxy things are really moving – was transferred to the remaining two, bumping them up to warp speed and throwing them violently outward from the center. As they jetted away at high speed, the larger of the two absorbed the other, creating the large, very speedy blue straggler we see today.
