How hot is the Sun, its surface and core? How long does it take the Sun's rays to reach the Earth? It is very hot there. This fusion process not only heats the Sun, it makes the sunlight we see here on Earth. This sunlight travels the speed of light which is 186,282 miles per second or 299,792,458 meters per second. This means the light from the Sun takes 8.4 minutes to travel 93 million miles to Earth. If the world's fastest land animal were to travel that same distance, it would take a cheetah over 151 years to reach the Earth running about 70 mph nonstop! Learn about Earth and space science, and have fun while doing it!

What is a light-year? Traveling at a speed where you cross nearly 200,000 miles every second for eight full minutes would only get you to the center of our solar system. A light beam needs only 8 minutes to travel the 93 million miles (150 million kilometers) from the sun to the Earth.

- Radiation from the Sun, which is more popularly known as sunlight, is a mixture of electromagnetic waves ranging from infrared (IR) to ultraviolet rays (UV).It of course includes visible light, which is in between IR and UV in the electromagnetic spectrum. Extreme Ultraviolet Sun.ow, since the average distance between the Earth and the Sun over one Earth orbit is one AU (about 150,000,000,000 m), then it will take about 8 minutes for radiation from the Sun to get to Earth. Actually, the Sun does not only produce IR, visible light, and UV.

- How long does it take to reach the sun? 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 th…e Sun in 101 days.   A Boeing 747 at cruising speed ~550 mph would take over 19 years.

Solar Radiation at Earth every square meter of Earth's surface would receive 1,368 watts of energy from the Sun. Although Earth does intercept the same total amount of solar EM radiation as would a flat disk of the Earth's radius (see figure below), that energy is spread out over a larger area. The surface of a sphere has an area four times as great as the area of a disk of the same radius.

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.

- During solar flares, the Sun also emits X-rays. X-ray radiation from the Sun was first observed by T. Burnight during a V-2 rocket flight. This was later confirmed by Japan’s Yohkoh, a satellite launched in 1991.ow, since the average distance between the Earth and the Sun over one Earth orbit is one AU (about 150,000,000,000 m), then it will take about 8 minutes for radiation from the Sun to get to Earth. Actually, the Sun does not only produce IR, visible light, and UV.

- 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 does it take sunlight to reach the Earth? The light reflected from the surface of the Moon takes only a second to reach Earth. The Sun is more than 8 light-minutes away. And so, if the light from the nearest star (Alpha Centauri) takes more than 4 years to reach us, we're seeing that star 4 years in the past.

How much time will take to reach the light rays from sun to earth I don't know the CURRENT distance between the sun and Earth, but the AVERAGE distance is 149,600,000,000 meters. Well distance equals speed times time, so time equals distance over speed. So we do 149,600,000,000 meters divided by 299,792,458 m/s which gives us 499 seconds, otherwise known as 8 minutes 19 seconds. That's how long it takes light to go from the sun to Earth. Oni_Kami.

Size of the Solar System It takes light 1 and 1/2 seconds to go from the Earth to the Moon, 240,000 miles. It takes 8 minutes for the light of the Sun to reach us. It takes 5 light-hours (meaning the distance light travels in 5 hours) for light to get out to Pluto from the Earth. When we leave our solar system, distances get very large. The nearest star, named Proxima Centauri, is over 4 light-years away.

How long does it take sunlight to reach the Earth? What you probably don't know, is that these photons striking your eyeballs were ACTUALLY created tens of thousands of years ago and it took that long for them to be emitted by the sun. Once they escaped the surface, it was only a short 8 minutes for those photons to cross the vast distance from the Sun to the Earth

How long does it take sunlight to reach the Earth? Since the last bit of light travels at the speed of light, the state right after must also travel at the speed of light. If the sun suddenly disappeared, it would stop shining light on the earth and the earth would go dark. But it takes 8 minutes and 19 seconds for the light from the sun to reach earth.

Solar Radiation & Photosynthetically Active Radiation The sun’s radiation must make it through multiple barriers before it reaches Earth’s surface. The first barrier is the atmosphere. About 26% of the sun’s energy is reflected or scattered back into space by clouds and particulates in the atmosphere 34. Another 18% of solar energy is absorbed in the atmosphere.

Sunlight The ultraviolet radiation in sunlight has both positive and negative health effects, as it is both a principal source of vitamin D 3 and a mutagen. Sunlight takes about 8.3 minutes to reach Earth from the surface of the Sun. A photon starting at the center of the Sun and changing direction every time it encounters a charged particle would take between 10,000 and 170,000 years to get to the surface.

How much sunlight hits the Earth? Atmospheric Science with 30+ answers. The Earth receives an average solar insolation of 1361 Watts per square meter at the top of the atmosphere. But since much of this radiation is attenuated, this figure drops to an average of around 250 Watts per square meter at the surface (this figure still ignores clouds, however).

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.

Light-year It takes 8.3 minutes for light to travel from the Sun to the Earth (a distance of 1.58 × 10-5 light-years). The most distant space probe, Voyager 1, was 13 light hours (only 1.5 × 10-3 light years) away from Earth in September 2004. It took Voyager 27 years to cover that distance.

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.

High School Earth Science/Telescopes A beam of light could travel from New York to Los Angeles and back again nearly 40 times in just one second. Even at that amazing rate, objects in space are so far away that it takes a lot of time for their light to reach us. Even light from the nearest star, our sun, takes about 8 minutes to reach Earth.
