STAR · the black hole's stopwatch
ORBITS Sagittarius A* every 16 yearsTOP SPEED about 7,700 km/s

The most famous star in the galactic center, whipping around our supermassive black hole every 16 years and reaching nearly three percent of light speed at closest approach. Astronomers tracked its complete orbit for decades; it proved the central mass is truly a black hole and tested Einstein's relativity in extreme gravity. A Nobel Prize rode on this star's back.
