  • Approximately eight minutes. So, if the Sun were ever to blow up, we wouldn't know until eight minutes later...
  • About eight minutes is "close enough for government work," but if you REALLY want to KNOW, the relevant facts are that the speed of light is almost exactly 186,000 miles per second, and the average distance of the earth from the sun--longer axis slightly more, shorter axis slightly less--is 93,000,000 miles. Simple arithmetic tells us that the travel time of light from the sun to the earth is therefore 500 sec., give or take a little, depending on the precise position of Earth on its orbital path--500 seconds working out to 8 min. 20 sec., + or - that little bit.
  • Approximatly it takes 20 minuits to travel, so the next time you are outside when the sun is out the ,light that is shining on you actually is 20 minuits old!
  • The sun is about 93,000,000 miles away and light travels 186,000 miles per second. Divide distance by speed and you get 500 seconds or 8.3 min.
  • Just from my Memory It was around 8 mins but others here have done the calculations they are getting around 8 mins so this is just to hit everyone home. ;)One more agrees its 8 something.
  • It takes 8 1/2 minutes for light to travel from the sun to the earth.
  • Light is, fundamentally, not direction biased. The speed of it is simply given by two key constants of free space (Square root of Eo/Uo, i think, off hand.) It relies on no frame of reference, etc. For light to travel from the sun to the Earth takes 8 minutes, and relying on this (which is Einstein's First or Second Relativity Postulate), light takes the same amount of time to return.
  • 5 hours
  • About 8 minute(500seconds)meaning if the sun could blow, we wouldnt know until 8 minutes later. proff:joseph hlanganiso.university of free state. R.S.A

This yields 500 s (8mn20s) Of course, were are measuring this after the light has really escaped from the sun. It takes a much longer time for the sun's energy to escape from the sun in the beginning. Remark that, as the average orbital speed of the earth is 29.783 km/s, the earth has travelled 14.891 km in that time, which is much more than the earth diameter. So if you were looking at the earth from the sun, you would see it at a totally different place than where it actually is.
  • Since light travels @ 186,282 miles per second, it would take 8.32 minutes.
  • Around eight minutes.
  • Eight and a half minutes roughly.
  • 8 minutes 23 seconds
  • It takes 8 minutes 23.56 seconds
