How do you measure the mass of the black hole at the galactic center?

If you observe an object in an elliptical orbit around something, AND you know the mass of the orbiting object AND the size of the orbit, you can calculate the mass of the object at the center (more precisely, at one of the foci) of the orbit.
We observe several stars orbiting the super-massive black hole at our galactic center. We can calculate their mass based on the light they give off, and we can measure their orbits over time. From this, we can calculate the mass of that black hole.

Where is the galatic center and its black hole?
The galactic centre is the central region of a galaxy. Most, if not all galaxies have a supermassive black hole at their centre.
What are straight branches of stars projecting from the center of galaxy?
Generally older stars. Most, if not all galaxies have a supermassive black hole at their centre.
Is the black hole a part of your solar system?
There is no black hole in our solar system.It is believed, however, that there is a black hole at the center of the Milky Way Galaxy, and that there are black holes at the center of every galaxy.
What is a sellar black hole?
Perhaps you mean stellar black hole. Stellar means related to a star, so that refers to a black hole that results from the collapse of a star. Actually that's the ONLY confirmed way to create a black hole (other ways are a bit hypothetical), but the term is also used to refer to a black hole which has approximately the mass of a star - to distinguish it from the supermassive galactic black holes in the center of most galaxies, as well as the intermediate-mass black holes found in star clusters.
Why does Sagittarius A indicate that a black hole is at the center of the universe?
Sorry, the universe does not have one center. According to the usual interpretation of the Big Bang theory, any and all points in the universe can equally be considered centers of the universe.Perhaps you meant to ask "Why does Sagittarius A indicate that a black hole is at the center of the Milky Way Galaxy?" instead. Galaxies do have distinct centers, all spiral galaxies are now believed to have a supermassive black hole at their centers, and our galaxy: the Milky Way is a spiral galaxy. The observations of the object called Sagittarius A match what would be expected of a supermassive black hole and are in the right galactic direction to place it at the center of the Milky Way galaxy.
Where is the galactic center in the constellation of Sagittarius?
The black hole Sag A* is considered to be at the center of our galaxy.
Where is the galatic center and its black hole?
The galactic centre is the central region of a galaxy. Most, if not all galaxies have a supermassive black hole at their centre.
If the sun goes to the center of the milky way in 2012 because of the galactic alignment will it be consumed by a black hole?
Let's take these fears slowly, one at a time.First, what is a "galactic alignment" ? ? ?
What object is believed to reside at the center of Active Galactic Nuclei?
The center of many galaxies is suspected to house a "supermassive black hole". The black hole may even weigh more than all the stars in that galaxy combined. Spiral galaxies are more likely to contain a supermassive black hole.
What is located in the middle of Milky Way?
The galactic center of the Milky Way is a compact object of very large mass (named Sagittarius A), strongly suspected to be a supermassive black hole.
Why is there is a black hole in the center of the galaxy?
Gravity. However, it isn't yet entirely clear how galactic black holes could grow to their current size in a relatively short time.
What has the author Tal Alexander written?
Tal Alexander has written: 'Stellar processes near the massive black hole in the galactic center' -- subject(s): Black holes (Astronomy)
What gets bigger when more is taken away?
a wormhole or black hole, the more matter it consumes or removes from its surroundings, the more its instability or mass increases, therefore its absorption power. Scientific studies say, and it is proven that, the Milky Way has a supermassive black hole in the center galactic, named Sagittarius A*. Many, if not all galaxies are believed to harbor a supermassive black hole at their center.
What is supermassive blackhole?
A supermassive black hole is a huge black hole, usually in the center of a galaxy. All or most galaxies are expected to have such supermassive black holes. Such a galactic black hole typically has over a million times the mass of our Sun; the largest (in large galaxies) have billions of times the mass of our Sun. The black hole in the center of our own galaxy (the Milky Way) is associated with the object Sagittarius A*, and it has a mass estimated at 4 million solar masses.
What is at the center of the black hole?
A singularity is at the centre of a black hole.
What are straight branches of stars projecting from the center of galaxy?
Generally older stars. Most, if not all galaxies have a supermassive black hole at their centre.
Is the black hole at the center of the milky way visible from earth?
Well, by definition, you couldn't see a black hole if it were sitting next to you.However, be that as it may, and it most likely is, the answer to the unspokenintent of your question is "No". We can't even see the effects of the putativeblack hole at the center of our own galaxy, because the line of sight from usto that neighborhood is obscured by so much galactic gas and dust.
