How many minutes are required for the sunlight to reach the earth if the sun is 1.50 x100000000000000000 km from the earth?

Answer 1

Just like any other trip, the time required depends on the speed at which you travel.

To Proxima Centauri at the speed of light . . . about 4.2 years .

At 60 mph, IF you could travel in a straight line . . . about 47 million years.

As you can see, your speed would make a difference.

Answer 2

It takes approximately 8 minutes and 20 seconds for sunlight to travel from the sun to the Earth, regardless of the specific distance. This is due to the speed of light, which is about 300,000 kilometers per second.

Answer 3

Roughly 81/3 minutes.

About 500 seconds (8 minutes 20 seconds)

(It takes a bit longer in July than in January due to the eccentricity of the Earth's orbit around the Sun).

The distance from the sun to the earth is approximately 93,000,000 miles (93million).

light travels at 186,232.397 miles per second.

thus dividing one by the other = 499.376056...

which is approx 8 minutes and 19 seconds..

Hence, if the sun "winked out" it would be slightly more than 8 minutes before we knew it.

From the sun, it takes 8 minutes for light to travel to Earth.

Answer 4

it is 8.33 minutes to reach the sun at light speed which is 1AU away appx 92-94 million miles away light travels at 186,000 miles a second.
186,000*60=11,160,000 miles a minute

92,000,000/11,160,000=8.2437 min
94,000,000/11,160,000=8.4229 min

8.2437+8.4229=16.6666/2=8.33 min is the mean time for light to reach the sun from earth or earth to the sun.

Answer 5

"The sun" never reaches the earth; but the heat and light from it do.

The average distance from the sun to the earth is 93 million miles.

The heat and light from the sun travel away from it at about 186,000 miles per second.

The time it takes them to reach the earth is about (93,000,000 / 186,000) = 500 seconds.

That's 8-1/3 minutes.

Answer 6

If you mean from the Sun, It takes a little over 8 minutes.

You can calculate it by dividing the distance travelled in kilometers by the speed of light, which is just very slightly under 300,000 km/second.

If you're talking about more distant objects where the distances is measured in light years, the answer is trivial: light travels 1 light-year per year.

However, astronomers generally prefer to use parsecs instead. Light takes 3.2 years to travel 1 parsec, so multiply the distance in parsecs by 3.2 to find the travel time in years.

Answer 7

From our perspective, it takes a bit over 4 years.

From the light's perspective, everywhere is the same place and every time is the same time, so no time at all. (Technically this is not QUITE true, since space isn't a perfect vacuum, but it's pretty darn close.)

Answer 8

The Earth is about 93,000,000 miles from the Sun. Light travels at 186,000 miles per second. So it takes light from the Sun about 500 seconds, or 8 minutes 20 seconds, to reach the Earth.

Answer 9

The distance to near-by stars is calculated through the parallax method.

Answer 10

Proxima Centauri, the closest star outside our solar system, is 4.2 light years away. so it will take 4.2 years for light to go from Earth to Proxima Centauri.
