A study was done with the measured parallaxes and motions of 10 massive regions in the Sagittarius spiral arm of the Milky Way where stars are formed. Data was gathered using the BeSSeL Survey with the VLBA, and the results were synthesized to discover the physical properties of these sections (called the Galactocentric azimuth, around −2 and 65 degrees). The results were that the spiral pitch angle of the arms is 7.3 ± 1.5 degrees, and the half-width of the arms of the M… WebAug 16, 2024 · Sagittarius A* has a Schwarzschild radius of about 18 million kilometers. The mass of a black hole can be determined by its gravitational force. Sagittarius A* has a mass of 4 million suns. Sagittarius A* is the most studied black hole in the world. It is the only black hole in the Milky Way that can be studied using optical telescopes.
