Sagittarius A* weighs 4 million solar masses, which is less heavy than what lurks within the cores of most galaxies. Still, that much mass is impressively crammed into a spherical volume with a radius of less than 13 million miles (21 million kilometers) — half of Mercury's orbit.Jan 19, 2015

How big is Sagittarius A?
22 million kmSagittarius A* / Radius
How big is Sagittarius A * compared to our sun?
Located 26,000 light-years from the Sun, our galaxy's central black hole, Sagittarius A*, has a radius about 17 times that of the Sun, meaning that it would sit well within Mercury's orbit.
How much mass does Sagittarius A have?
The mass that results from the study of this star and other nearby stars is 4 million solar masses! The only type of object that astronomers believe can have a mass of approximately 4 million stars, but a radius of about 100 AU, is a black hole.
How fast is Sagittarius A * spinning?
3.2 Unique spin parameter For instance, 31.4 min is used for Sgr A* and periods of lower HF-QPOs are used for the Galactic X-ray sources.
Is Sagittarius A The biggest black hole?
At the center of the Milky Way is a supermassive black hole, 4.3 million times bigger than the sun, known as Sagittarius A*. Until recently, it was not clear how much of the matter at the heart of the galaxy was Sagittarius A*. Astronomers measured the velocities of four distant stars around the black hole.
What is a black hole fact?
Black holes formed by the collapse of individual stars are relatively small, but incredibly dense. One of these objects packs more than three times the mass of the sun into the diameter of a city. This leads to a crazy amount of gravitational force pulling on objects around the object.
How heavy is a black hole?
A typical stellar-class of black hole has a mass between about 3 and 10 solar masses. Supermassive black holes exist in the center of most galaxies, including our own Milky Way Galaxy. They are astonishingly heavy, with masses ranging from millions to billions of solar masses.
How deep is a black hole?
In the case of a black hole, depth has no meaning. That is because by definition, all black holes cause a disturbance in the space-time continuum. First of all, there is a point called the "even horizon" past which nothing can be seen.
