Web8 okt. 2024 · In astronomy, the stellar mass of a galaxy is the total mass of all its stars. It is usually measured in terms of the solar mass, which is the mass of our Sun. The stellar mass of the Milky Way is estimated to be between 200 and 400 billion solar masses. A model is created of hypervelocity stars that have been ejected from the galaxy. WebIf we know a star's orbital period and orbital radius, we can use Newton's version of Kepler's third law to determine the mass of the galaxy, with a minor warning: We get only the mass of the galaxy within the orbit of the star we examine. What we have learned from our studies to find the distribution of mass in the galaxy is that the stars in the galactic disk …
