True.
Now, whether or not it's sad that I know the temperatures of both the Sun and the Earth to three significant figures off the top of my head is another issue entirely. And at least I didn't go into how the Earth's temperature differs from that of a blackbody at 1 AU from the sun due to the albedo of the Earth (-) and the non-anthropogenic greenhouse effect (+), or how the effective temperature of the Sun is figured, given that the actual temperature does vary from about 4000K at the top of the transition layer (where the opacity of the overlying gases is ~5% or less) to about twice that at the bottom (where the opacity is ~95% or more), only some 400km (250 miles) deeper in the photosphere . . .
