what is The diameter of Quasar?

Answer 1

They are assumed to be larger than stars but smaller than galaxies, but we really don't know for sure. They are too far away can are only seen as mere specks, even in large telescopes.

Answer 2

The diameter of a quasar is an issue thats long been a question among scientists today. However what is definately known is that quasars are much smaller than what you'd expect find of an object just as luminous and just as far away as the quasar.

The size of a quasar is measured by the pulsing radiations that they emit. These pulses are similar to pulses of light emitted by pulsars.However, this method of calculating the diameter of a quasar is subject to a lot of speculation

Infact quasars several MegaParsecs away are visible using the simplest of amateur equipment !!!!

Answer 3

Which quasar? There is more than one.

Since quasars are likely the very active nucleus of distant galaxies, they are small (perhaps no more than a few light-months across based on the observations that some are slightly variable within a few months).
