I was wondering, is the surface of Venus so hot that it would glow red in the dark (e.g. on the dark side of Venus)? I am working on making a solar system simulator, and that would make for a great level if it is accurate.

The average surface temperature on Venus is 462 °C. You would need a temperature above 800 °C before you would notice any light.

Here are some calculated radiation outputs of the surface temperature of Venus, a 1000 °C black body and the sun.

I found this reference that shows it can be seen as low as 500 °C, which is still above (but very close to) your stated average of 462 °C on Venus. Therefore at least on average, the surface probably still would not glow. However, I wonder if there are still parts of Venus that would be this hot (e.g. possibly the equator)? hypertextbook.com/facts/2000/StephanieLum.shtml –  Jonathan Jun 23 at 17:24

Simple answer: No, the only place on Venus's surface where visible light is emitted from rock is in the lava flows.
