How heavy is a quasar?

Answer 1

When you talk about astronomical objects, it is usually more appropriate to talk about their mass, not their weight.

A quasar is powered by a supermassive black hole; those have a mass of millions or billions times the mass of our Sun.

Answer 2

Excellent question, and the answer is "We don't know, but it varies". We're not even sure what a "quasi-stellar radio source", the full name for "quasar", really is.

The current belief, based on our current understanding of stellar physics, is that a quasar is the region around a super-massive black hole at the center of a distant galaxy. As matter is accelerated to near lightspeed by falling into the black hole, it interacts with other matter and emits X-rays and strong gamma rays.

Answer 3

A quasar is currently believed to be caused by the supermassive black hole which exists in the centers of galaxies. Those black holes have masses of millions, or even billions, times the mass of our Sun - depending on the size of the galaxy. Larger galaxies have larger central black holes.

Answer 4

A quasar is not a physical object that has weight, as it is a highly energetic and distant celestial object powered by a supermassive black hole at the center of a galaxy. The mass of a supermassive black hole in a quasar can range from millions to billions of times the mass of our sun. However, it is important to note that the weight of a quasar itself cannot be accurately determined due to its complex nature and distance from us.
