- The light travels 300,000 kilometers in every second, then to travel 149,600,000 kilometers needs 498.6 seconds. This is the approximate time it takes light to reach the earth, by which the light that reaches us from our star had to take all that time so that all who inhabit this planet can enjoy it and its heat. writing science sun planets light. 3 months ago by.

- Q-Star. The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth.……..Here's the math. 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.his 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.

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.

Why does it take 14 minutes for the information to reach Earth from Mars even though signals travel at the speed of light? In this position it takes 24 minutes for information to travel because Earth and Mars are 24 light minutes. So on average the Earth and Mars are 14 light minutes away so on average a message from Mars would take from 4 to 24 minutes to reach Earth.

Why does it take 14 minutes for the information to reach Earth from Mars even though signals travel at the speed of light? Because that's how far away Mars is! The speed of light is roughly 300,000 km/second. Mars is on average about 225 million km from Earth (the distance varies greatly, depending on both planets' position in their orbits). That translates to an average distance of 12.5 light minutes. It can vary from about 4 minutes to 24 minutes, depending on Mars's current distance from Earth.

Traveling at light speed, how long would it take to get to the nearest galaxy?  (Beginner) 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. That's because of relativistic time dilation, as explained here.

How long does it take light from the sun to reach Earth's surface? Best Answer: The earth is approximately 93,000,000 miles from the sun. Light travels at 186,000 miles per second. Divide 93 million by 186,000 and you get 500 seconds.Divide 500 by 60 to get the minutes and it comes out 8.33 minutes.or a person on Earth's surface, at a latitude of almost 23 South, on Jan. 3, with the Sun at the zenith: the closest point on the Sun's surface is at 146,390,959 km Time = 488.3 s = 8 m 8.3 s That is the fastest that light from the Sun could have reached a spot on Earth's surface in 2007.

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.That is why you'll hear astronomers say that when we are looking at stars, we are looking back into the past.eport Abuse. That depends on how far away the star is. The closest star is Alpha Centauri, which is about 4.37 light years away. So it takes 4 years and 3 months for light to reach us from Alpha Centauri.

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.

How long does it take light to travel around Earth seven and a half times? About a second. The circumference of Earth is about 40,075 km. Light travels at about 299,792 km/s. So to find how long it takes to go around 7.5 times, we multiply the circumference of the Earth by 7.5.Then take that answer and divide it by the speed of light, which equals 1.0026 seconds.ight travels at about 299,792 km/s.

- How long does it take the light reflected from the moon to reach the earth?   light travels at 300,000,000m/s, the moon is roughly 375,000,000m away, so it takes light about 1.25 seconds to reach one from the other.etired US Navy officer, astronomy buff, history nut. Betelgeuse is a red supergiant star about 640 light-years from Earth. So light from Betelgeuse takes 640 years to get here. Here's an interesting fact; the star Betelgeuse is probably near the end of its life, and may explode in a supernova explosion any time.

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.

- Tire Rotation. Naturally, the treads on your tires wear down with time for many reasons. Besides the wear that normally occurs over thousands of miles, the alignment of your front wheels can cause those in front to wear prematurely. Most people are aware it happens but wait too long before replacing their tires.

- Even though it would take light from the explosion eight minutes to travel from the sun to the earth, in Newton s theory knowledge that the sun had exploded would be instantaneously transmitted to the earth through the sudden change in the gravitational force governing its motion.ence, the first matter from the Sun would take about 22 hours to reach the Earth. During this time, according to both general relativity and Newton s theory of instantaneous gravity, there would be no appreciable change in the Sun s gravitational pull on the Earth.
