Milky Way Galactic Center Star Orbit Tracked at Three Percent Speed of Light

A star near the center of our galaxy reaches almost 3 percent of the speed of light as it whips around something four million times the mass of the Sun that emits no light of its own, according to findings from Space Daily and UCLA media reports. Tracking this stellar orbit for nearly three decades provided the empirical baseline that illuminated the extreme gravitational dynamics operating at the heart of the Milky Way.

The Tech TL;DR:

  • Milky Way Dynamics: A star near the galactic center accelerates to roughly 3 percent of light speed orbiting a massive dark object.
  • Invisible Mass: The central entity possesses a mass four million times that of our Sun while emitting zero light.
  • Long-Term Astrometry: Continuous tracking over nearly thirty years enabled unprecedented precision in mapping stellar trajectories near supermassive black holes.

Decades of Astrometric Tracking and Data Processing

According to UCLA media reports, mapping the extreme environment surrounding the galactic center demanded nearly thirty years of meticulous observation. This observational longevity allowed scientists to capture complete orbital periods for stars darting around the central gravitational well.

Probing the Supermassive Dark Object

Per Space Daily reporting, the entity governing these extreme stellar velocities is four million times the mass of our Sun yet remains entirely dark across the electromagnetic spectrum. This invisible anchor exerts immense tidal forces, accelerating nearby stars to a fraction of light speed during their closest approach.
