<Rainer Schödel> led a study that traced a short-period <star> around <Sagittarius A*> at the center of the <Milky Way>. Ten years of high-resolution <astrometry> captured both the nearest and farthest parts of the <star>'s highly eccentric <orbit>.
The 2002 analysis found an <orbital period> of about 15 years and a close approach of only about 17 light-hours. Concentrating several million <solar mass>[solar masses] inside that small region excluded plausible extended clusters as the source of the central gravitational field, strengthening the <supermassive black hole> interpretation.<Closest Star Seen Orbiting the Supermassive Black Hole at the Centre of the Milky Way by Rainer Schödel and others>[Abstract: observed orbital coverage, period, pericentre and excluded extended-mass alternatives]{ref}
