How To Calculate The Mass Of A Star – BosCoin

WebThe supermassive black holes in the centers of galaxies can often be measured using this method. For example, the mass of the black hole in the center of our Milky Way galaxy was calculated by measuring the speeds of individual stars that orbit around it. This showed that the black hole is three million times more massive than our Sun. WebThe mass of the Milky Way Galaxy is estimated to be 8.5 × 10 11MSun, and so our Milky Way is turning out to be somewhat smaller than Andromeda. Elliptical galaxies do not rotate in a systematic way, so we cannot determine a rotational velocity; therefore, we must use a slightly different technique to measure their mass. black and decker customer service contact
