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.

  • $\begingroup$ 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 $\endgroup$ – Jonathan Jun 23 '14 at 17:24

    $\begingroup$ Old question I realize, but Venus' equator and Venus' north and south poles are the same temperature. The planet traps heat efficiently enough that the temperature is consistent at any latitude and any season. $\endgroup$ – userLTK Apr 21 '15 at 8:51
