Types of black holes.

There are a lot of mysteries which revolves around a black hole. Nobody has ever seen a black hole but we certainly know a thing or two about black holes. So following are the multiple types of Black Hole : -

1. Stellar black hole.

Stellar black hole or stellar mass black hole forms when a massive star dies. For a star to form a black hole, it has to be multiple times greater than "our" sun as our sun is way too small to form a black hole when it runs out of fuel. Generally a stellar black hole has about 3 to 10 solar masses. Most of the black holes found till now fall under the category of stellar mass black hole.

2. Supermassive black hole.

It is a rarely found black hole mostly located in the centre of the galaxies including our own. As of now, we don't know how a supermassive black hole forms. A supermassive black hole has its mass ranging from millions to billion solar masses. Although we don't know how a supermassive black hole comes into existence, scientists have a good idea about it. As per the scientists, they are so "supermassive" because they are present in the centre of a galaxy, as there are a lot of stars, gases and dusts that provides an unending supply of materials for the black hole to grow larger and being at the centre of a galaxy provides a better chance to collide and merge with another smaller black hole.

3. Intermediate black hole.

Intermediate black holes are the black hole which is greater than the stellar black hole but smaller than the supermassive black hole. It is a hypothetical black hole as scientists haven't found any existing intermediate black hole. It is believed that their mass range is between 100 to 1 million solar masses. There are only two possible scenarios for a black hole to grow this big i.e to devour other smaller black hole or to consume lots and lots of materials like gases and dusts.
