How far can sunlight reach?

Answer 1

The Sun is approximately 93,000,000 miles (150,000,000 km) or 1 AU (Astronomical unit) from Earth. Light would take 8.3 minutes. Voyager 1 ~38,000 mph would reach the Sun in 101 days. A Boeing 747 at cruising speed ~550 mph would take over 19 years. An average car ~@ 70mph, would get you there 152 years later. (… and require over 2.5 million gallons of fuel) On a horse ~30 mph, it would be grey (and dead) 354 years later. By foot: At ~3 mph, you would reach the Sun in - wait for it. 3,540 years.

Answer 2

It is different for each star, as it depends on how far away the star is. Whatever the star's distance in light years is the number of years it takes for its light to reach us. The nearest star other than the sun, Proxima Centauri, is 4.2 light years away. The varthest that can be seen without a telescope are more than 1,000 light years away.

Answer 3

Eventually when a star has used all its energy up and becomes a dead lump of matter it could be as cold as "empty" space. That's about -270ºC minimum. (Or +273 Kelvin, because of the cosmic background radiation.)

But the coldest star to date found is 97ºC. That is not much hotter than a normal cup of coffee and its been named as CFBDSIR 1458 10b. It is a "brown dwarf star" and it is believed it lacked the mass to become a "real" star.

Answer 4

i believe the lowest it has ever been is -300000 degrees celcius that or without the minus cuz i really wasnt payin attention in class yesterday don't get me wrong im guessing you werent either even tho i go to tv lava lamp high school in Antarctica where it is to hot to think

Answer 5

WeekendWarrior44: actually I calculated everything myself and if u walked at an average speed of 72 meters per minute non stop it would take 3,948.11593 years 3,948.11593 = 205,302.028 weeks = 1,437,114.2 days = 34,490,740.8 hours = 2,069,444,000 minutes = 124,166,700,000 seconds

Answer 6

Light is a form of energy that travels at 300000km every second.even though it travels so quickly, it still takes 8 minutes to reach us from the sun. So, if the sun stopped shining right now, we probably wouldn't notice until 8 minutes later, when we'd be left in the dark.

Answer 7

Depends on the speed you travel. At the speed of light it would take 8 minutes. Sorry but if your going to ask a question be more specific. And we have already sent ships into orbits closer then mercery, so technically we have gotten really close. Why is your question stated in terms of what will happen not what would happen.

Be more specific and get the time correct, unless your planing to actually go there...

Answer 8

Earth take 24 years to get to the Sun.......

Answer 9

It depends on the speed at which you are travelling.

At the speed of light, it takes on average 8 minutes 19 seconds, or approximately 1.58x10-5 Earth years.

Answer 10

The sunlight can reach 1500billions km due to its intensity becomes fall gradually.
