There are no perfect black bodies on the universe. But there are a lot of them which can be approximated (with good precision) by the black body description.
What is a perfect black body?
A perfect blackbody absorbs all radiation incident on it and It emits electromagnetic radiation in the form of thermal radiation from its surface. OR A perfect blackbody is a perfect emitter and perfect absorber.
What is a perfectblack body?
If it is capable of emitting and absorbing radiations having wavelength right from 0 to infinite, then it is declared as perfect black body. Sun is a black body. Now it is in the emitting phase.
Why does some object appear black?
It's one of the colour. Black colour absorb all colour. A perfect black body radiates heat.
Is the filament a good approximation of a black body?
The properties of a filament do not perfectly match those of a black body radiator, as a filament has a limited temperature range compared to a black body. A black body is an idealized concept that absorbs all incident radiation and emits it as thermal radiation at all wavelengths. While a filament emits thermal radiation when heated, it may not fully exhibit the characteristics of a black body.
