The relevant quantity in this case is the mass. The mass of our galaxy's black hole is estimated to be about 4 million times the mass of the Sun. (If you want that in kilograms, look up the mass of the Sun, and multiply that by 4 million.)

You have heard rumours of a giant Black Hole in the center of your Galaxy and im curious how big would the star of been to create it. Normal stars leave them te size of a pea.?

Most galaxies have a gigantic black hole in their center. The black hole in the center of our galaxy is estimated to have 4 million times the mass of our Sun. Some larger galaxies have black holes with billions of times the mass of our Sun. It is not yet understood how such a large black hole could form.


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.

What is the difference between a black hole and a quasar?

A quasar is a galaxy the gives off huge amounts of radiation, sometimes having a black hole at it's center. A black hole is a dead star that was big enough to "curl back in itself, like a snake eating it's tail."1 Or picking oneself up and carrying yourself by your bootstraps.One is a single star, one is a galaxy.(1 my words)


What can be found in the center of a quasar?

A big black hole.

Which star in the galaxy is a giant?

There are lots of giants in our galaxy. Betelgeuse is very big (about 20 of our Suns). The massive object / system (expected to be a supermassive black hole) at the center of the Milky Way has the mass about 2.6 million of our Suns.
