How Long Does it Take Sunlight to Reach the Earth? Sunlight travels at the speed of light. Photons emitted from the surface of the Sun need to travel across the vacuum of space to reach our eyes. The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth.

It takes light about 8 min. to travel 1 AU Calculate how long it takes light from each planet to reach the sun It takes light about 8 minutes to travel one AU. Calculate how long it takes light to reach each planet from the sun. Planet and distance from sun in AU's Mercury 0.39 Venus 0.72 Earth 1.0 Mars 1.5 Asteroid belt 2.5- 2.8 Jupiter 5.2 Saturn 9.2 Uranus 19.2 Neptune 30.0 Pluto 39.4.ating Newest Oldest. Best Answer: Sample calculation for Mercury: Use a ratio. Say: Light takes 8 minutes to travel 1 AU, so it takes x minutes to travel 0.39 AU. To put that in equation form: 8/1 = x/0.39 And solve for x: 0.39 * 8 = x 3.12 = x Light takes 3.12 minutes to travel to Mercury.

General Astronomy/Print version If the Sun were to suddenly vanish at this very moment, the light from the Sun would continue to arrive for the next 8.5 minutes which is the travel time from the Sun to the Earth at the speed of light. There would still be a Sun in the sky even though the Sun is actually not there now.o far as we know, and so far as the little data we have can tell us, gravity and the force of gravity also travels at the speed of light. This means the Sun's gravitational force takes 8.5 minutes to cross the solar system to get to the Earth and affect the orbit of the Earth.

How Long Does it Take Sunlight to Reach the Earth? Divide these and you get 500 seconds, or 8 minutes and 20 seconds. This is an average number. Remember, the Earth follows an elliptical orbit around the Sun, ranging from 147 million to 152 million km. At its closest point, sunlight only takes 490 seconds to reach Earth. And then at the most distant point, it takes 507 seconds for sunlight to make the journey.

How long does it take light to get to earth from the sun? do u also know about heat? ? Light moves at 186,000 miles a second and the Sun is 93,000,000 miles away. Do the math. (500 seconds or 8 1/3 minutes) Heat is energy. Heat from the Sun is brought to Earth in the light from the Sun. Sunlight is absorbed by things it strikes, like the ground, and the energy of the light becomes heat energy in the thing that absorbed it.

How long does it take for the suns rays to reach earth? When we're at perehelion (min distance, around January 4th), it takes about 8 mins and 11 secs. Average time: 8 mins and 20 secs. The Sun's rays take 8.3784 minutes to reach the Earth, if you take the average distance between Sun and Earth. Only the Sun's warmth is slower than light, it's warmth takes about a week or two to reach the earth. Time = distance ÷ velocity The solar is approximately a million.496 * 10^11 meters from the earth.

Why does it take 14 minutes for the information to reach Earth from Mars even though signals travel at the speed of light? The distance to Mars is significantly more than the distance to anywhere else on Earth. So for light to travel that distance it takes a delay of 14 minutes (this varies depending on how earth and mars are positioned).

How long does it take for a star's light to reach the earth? Asker's rating. Report Abuse. It depends on the distance between the earth and the star, the sun's light takes only 8 minutes to reach us, but other stars are much further away and take years at least for their light to reach us.superpsychicman · 9 years ago.Thumbs up.he distance between stellar objects is measured in light years which is the distance light travels through vacumn in a year. So if a star is four light years away it would take 4 years for the light to reach earth.
