How much does a black hole weigh?

Black holes can vary significantly in weight, depending on their type. Here’s a breakdown of their masses:

Types of Black Holes

• Stellar Black Holes: These form from the collapse of massive stars and typically weigh between 5 to 20 times the mass of our Sun.
• Supermassive Black Holes: Found at the centers of galaxies, these giants can weigh millions to billions of solar masses. For example, the supermassive black hole in the Milky Way, known as Sagittarius A*, is about 4 million times the mass of the Sun.
• Intermediate Black Holes: These are less common and weigh between 100 to 100,000 solar masses. Their existence is still a topic of research.

Understanding Mass Measurement

The weight of a black hole is often described in terms of solar masses, which is a standard unit based on the mass of our Sun. Scientists use various methods, such as observing the motion of nearby stars and gas, to estimate the mass of a black hole.

In Summary

Black holes can weigh anywhere from a few times the mass of the Sun to billions of solar masses, depending on their type and formation history.
