| S2 and Central Black Hole (1535 words) |
 | The astronomers believe, however, that the stars did form too far from their present location because the seven massive stars must be less than 10 million years old, or they would have exploded already since such massive stars do not live that long. |
| The seven stars are the remains of what likely was once a much larger and massive cluster of many stars, possibly a globular cluster where a middleweight fl hole could develop through runaway star collisions, as indicated by other research. |
| The star orbits the galaxy's central fl hole at an average distance of 5.5 light-days that takes about 15.2 years to complete, at "an inclination of 46 degrees with respect to the plane of the sky" (MPE research introduction). |
