How Long Does it Take Sunlight to Reach the Earth? We orbit the Sun at a distance of about 150 million km. Light moves at 300,000 kilometers/second. 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. But the story of light gets even more interesting, when you think about the journey light needs to make inside the Sun.

- In our Solar System, we see light from our sun reflected off the planets. In more distant galaxies, light from many millions of stars takes a long time to reach the Earth. It takes light 4 years to reach the Earth from Sirius, a near neighbouring star. Using the Hubble telescope, we can see the light from the Eagle Nebula, which takes 7,000 years to reach the Earth.

How long would it take to travel around the world at lightspeed? How Fast is the Speed of Light? Light travels at a constant, finite speed of 186,000 mi/sec. A traveler, moving at the speed of light, would circum-navigate the equator approximately 7.5 times in one second. By comparison, a traveler in a jet aircraft, moving at a ground speed of 500 mph, would cross the continental U.S. once in 4 hours.

How long does it take light from other stars to reach Earth? Report Abuse. That depends. Distance from the earth to stars is measured in light years. It takes a ray of light (light travels at 186,200 miles per second) one year to reach the earth. So a star that is 10 million light years away...it takes 10 million years to reach earth.

How Long Does It Take to Get to Mars? Light travels at approximately 186,282 miles per second (299,792 km per second). Therefore, a light shining from the surface of Mars would take the following amount of time to reach Earth (or vice versa):n January 2006, the probe left Earth at 36,000 mph (58,000 kph). The time it would take such a probe to get to Mars would be: 1  Closest approach: 942 hours (39 days). 2  Farthest approach: 6,944 hours (289 days).

It takes light about 8 min. to travel 1 AU Calculate how long it takes light from each planet to reach the sun Rating 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.Do this same thing for all the planets.8 = time / distance.ating Newest Oldest.

How long does it take light from the Sun to reach Earth? Earth's distance from the Sun varies between about 147 and 152 million kilometers. Given the speed of light as 299,792,458 m/sec and the Sun's radius of 696,000 km, this makes the time taken for the journey (from the Sun's surface to the Earth's) between 8.14 and 8.42 minutes.

1 light year is equal to how many years of the Earth? Light travels at 300,000 kilometers per second, and the distance it travels in a single year is 9,460,730,472,580.8 kilometers. That’s a light year. So, for example, the star Alpha Centauri is 4.467 light years away from us, so a beam of light would take 4.467 years to get from Earth to Alpha Centauri.

FAQ - Spacecraft The short answer is the speed of light. It takes light 8 minutes to get from the Sun to the Earth (actually 8.33). So, for example, if Mars is 0.5 AU from Earth, it would take about 4 minutes for the information to get to Earth. If Earth and Mars are not lined up on the same side of the Sun, it could take as long as 20 minutes. That is the simple answer.

How long does it take for the Sun's light to reach us?  (Beginner) The time it takes for light to reach planets in our Solar System (not the Milky Way, which is our galaxy) varies from about 3 minutes for Mercury, to about 5.3 hours for Pluto. There is nothing out in space to prevent the sun's light from going infinitely far, in principle. In practice, the sun is only 4.5 billion years old, so its light can only extend 4.5 billion light years away from us right now. But there's nothing to stop that light from expanding outwards forever, as time goes on.

Traveling at light speed, how long would it take to get to the nearest galaxy?  (Beginner) Thank you for you greatly, appreciated, time. The closest galaxy is the recently discovered Canis Major dwarf galaxy, which is only 25,000 light-years away. So it would take 25,000 years to get there if you traveled at the speed of light. Actually, that's the amount of time it would take from the perspective of the outside world. From the perspective of a traveler moving at the speed of light, it would appear to take no time at all.

Light But we soon learn that light is more complex than this. Light arrives on our planet after a speedy trip from the Sun, 149 million km (93 million miles away). Light travels at 186,000 miles (300,000 km) per second, so the light you're seeing now was still tucked away in the Sun about eight minutes ago.
