This surface radiates 6.320e+7 W of thermal power.
Because power scales with T^4, doubling the temperature increases radiated power by a factor of 16 (2^4). Small temperature changes have an outsized effect on emission.
At 5778 K, the peak emission wavelength is 502 nm, which falls in the visible light portion of the electromagnetic spectrum.
An emissivity of 1.00 means this surface behaves very close to a perfect black body, emitting nearly as much radiation as physically possible for its temperature.
