What is the name of the supermassive black hole at the center of our galaxy?
Sagittarius A* The Milky Way's supermassive black hole, known as Sagittarius A* (Sgr A*), is over 4 million times more massive than our sun. Its strong gravitational pull draws nearby stars and gas clouds into its accretion disk.
Then, what law do astronomers use to estimate the mass of the black hole at the center of the milky way?
Kepler's 3rd law the theory: Kepler's 3rd law. How do theories of the origin of the Milky Way explain its halo quizlet? How do theories of the origin of the Milky Way explain its halo? Originally, the Milky Way started off as a spherical cloud of gas, stars, and star clusters. Over time, this sphere contracted toward its equator until it was a flat disk. The Milky Way's halo is the remnants of the spherical shape before it flattened.
How many stars does the Milky Way galaxy have?
The Sun belongs to a galaxy called the Milky Way. Astronomers estimate there are about 100 thousand million stars in the Milky Way alone. You can also ask where are many metal rich stars found in the milky way? spiral arms Population I stars Population I, or metal-rich, stars are young stars with the highest metallicity out of all three populations, and are more commonly found in the spiral arms of the Milky Way galaxy.
Accordingly, what kind of object do we think lies at the center of the milky way galaxy quizlet?
The orbits of stars in the center of the galaxy indicate that the presence of 3 to 4 million solar mass object in a region no larger than our Solar System. How does the diameter of the disk of Milky Way Galaxy compare to its thickness? You can also ask what lies in the center of galaxies? The Galactic Center (or Galactic Centre) is the rotational center, the barycenter, of the Milky Way galaxy. Its central massive object is a supermassive black hole of about 4 million solar masses, which powers Sagittarius A*, a compact radio source which is almost exactly at the galactic rotational center.
- What is the galactic center of our galaxy quizlet?
The Greek philosophers Leucippus and Democritus proposed a model for an atomic theory in the fifth century B.C. 1. atoms are separated by empty space through which they move
- Is Sagittarius A the center of our galaxy?
Earthquakes would be rare without the subduction zones, and even then, they wouldn't be very powerful. Most of the time, volcanoes are out of commission since they are usually caused by tectonic activity.
