Solar eclipse question [closed]

4

$begingroup$

In a solar eclipse, are we seeing it as the eclipse takes place in real time, or do we see it 8 minutes after it happens because that’s how long the light takes to travel from the sun?

  Welcome to Space Exploration! This is a good question, but probably better placed on astronomy.StackExchange - would the moderators consider moving it there? - In one of Jan Meeus's books, there's a chapter discussing similar topics at length (focusing on planet occultations, with some surprising answers!), but I don't have the books near me at the moment.

  @GNiklasch I typically suggest them in flags, so they will surely see it.

  "real time" is a fraught term when light speed and astronomical distances are involved ;-).

The Moon's orbit radius is about 384 400 km says wikipedia. Hence the sunlight eclipsed by the Moon reaches the Earth 1,28 s after passing close by the moon.
