WebMar 14, 2024 · 4. Cosmic Microwave Background is the most perfect black body that have been observed - it has near ideal Planck spectrum at temperature of 2.7 K. Assuming the theoretical prediction that black holes emit Hawking radiation, it would also be a black body radiation, but it was never observed. WebThe planetary equilibrium temperature is a theoretical temperature that a planet would be if it were a black body being heated only by its parent star. In this model, ... it may be useful to approximate the host star's radiation as a blackbody as well, such that: ... Similarly, Earth has an equilibrium temperature of 255 K (−18 °C; −1 °F
