what about the hawkin radiation it emits?
Actually I hv no idea about these radiations becoz till now we havnt been taught about this ....but acc to net it does not originate from beyond the event horizon, but is a consequence of the interaction of the strong gravitational field outside the horizon with the vacuum.
owhhh well thanks for the help. :-)

Heya folk !!
Here's the answer you are looking for
First of all, nothing in reality can be considered as a perfect black body.
Here is the answer:
An object is said to be a black body if it absorbs all the radiations around it and then that energy is re-emitted over a wide spectrum. This is known as black body radiation.
But in case of a black hole, it absorbs all the radiations around it. But unfortunately, none of the radiations can escape it because of its vast gravitational pull.
Since, black hole just absorbs energy and doesn't re emit it, I think, it cannot be considered as a black body.
