| Oct 20, 2021 at 1:37 | comment | added | uhoh | @Solon at this point I think you can either post an additional answer here or write a new question. I'm comfortable with my common-sense based answer and won't be pursuing this for you. | |
| Oct 20, 2021 at 1:34 | comment | added | Solon | Here are calculated values for some planets and our Moon: Moon 4800 lux Mercury 28500 Venus 53000 Mars 2750 Jupiter 700 How do these values compare with actual measured ones? The numbers are from a volume of documents entitled "Orbital Imagery for Planetary Exploration." | |

| Oct 19, 2021 at 20:58 | comment | added | uhoh | @Solon I have a table inclined by a few degrees from local horizontal. Do I need to measure the coefficient of static friction of my coffee cup and he exact inclination of the table's surface before I dare set my coffee cup down on the inclined table, or do I conclude "obviously flat enough" and go ahead and set it down? | |

| Oct 18, 2021 at 21:31 | comment | added | uhoh | @Solon one is facing a matte white surface illuminated by sunlight 30% brighter than noon on Earth's surface at the equator. The number doesn't matter, it's really bright! | |
| Oct 18, 2021 at 19:02 | comment | added | Solon | "Now imagine being accustomed to that level of illumination ..." So what level was that illumination, in Lux? I can find no actual measured illumination levels apart from one during the Apollo 8 mission for the sunlit portion of the far side, showing 160-320 lumens with the spot meter. | |
| Oct 18, 2021 at 18:55 | comment | added | Solon | Well, I cut and pasted that statement from somewhere on this site, maybe I'm getting senile in my old age? | |
| Oct 18, 2021 at 0:46 | comment | added | uhoh | @Solon I don't see that quote anywhere here except in your comment. Did you put it under the wrong post? Or was another comment since deleted? It sounds interesting! | |
| Oct 17, 2021 at 23:42 | comment | added | Solon | "Astronaut Dave Scott did see few bright stars on the lunar surface but only when standing in the shadow of the LM for some time with his visor up." Do you have a reference for him saying that? | |
