| I'm going to continue the discussion on this thread.
If you had a good enough spacesuit to stand/float on the sun, would it be daytime or nighttime?

| Assuming you started your mission from Earth, I guess UTC should be used, or a Mission Elapsed Time, which I believe use a conventional daytime anyway. So it depends on your arrival time.

| On the Sun, the Sun is never in the sky, so technically it is always nighttime on the Sun?

| Watsisname, Perhaps nighttime shouldn't be when the sun is in the sky, rather if it is visible at all...
No wait, that would mean if you are inside a building it's nighttime. Let's define it by light then.
No wait, some objects in the oort cloud would have perpetual night. Maybe, it should just be defined by logic.
This is a complicated topic...

| Watsisname, Actually, it depends on your definition of nighttime on the sun. Nighttime on the sun could be defined by sunspots, rotation of the sun, or by convection cycles. Also, may be impossible, but, Hornblower's day/night cycle could perhaps be created by a giant sunspot moving across the surface of the sun.

| Hahaha, this is simultaneously an interesting and weird thing to talk about.
I think the most precise and functional definition of "night" is "when the Sun is below the horizon of the celestial body you are on". If you are standing on the Sun, the Sun is below your horizon. And think about it -- what would the sky look like if you could stand on the Sun?
