S301's Record Speed Around Sagittarius A*
GRAVITY+ discovered S301 using Chile's VLT Interferometer.
S301 completes an 8.7-year orbit at 12 AU, 10x closer than S2.
Sgr A*'s spin is measured for the first time via S301.
Lense-Thirring effect will shift S301's orbit in 10 years.
S301's orbit is stable, with no immediate decay risk.
