The light takes about 640 years to reach Earth, as Betelgeuse (a red supergiant star) is about 640 light years from Earth.
Betelgeuse is approximately 430 light years away, or a bit over 3.7 million light hours.
it does reach the earth in light energy.
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. Very massive stars like Betelgeuse live fast and die in under 100 million years, and Betelgeuse will probably go supernova within the next 10,000 years. This is like no time at all in cosmic terms, but in terms of a HUMAN lifetime, it probably will NOT happen while we're alive to see it. But it could. In fact, Betelgeuse might have exploded 500 years ago, and we wouldn't know it for another 140 years!
If you mean light from the Sun, then it takes eight minutes for the light to reach the Earth.
From the sun, it takes 8 minutes for the light to reach Earth.
the light speed are very fast so light easily reach on earth
8 light years to reach earth.
It takes approximately 1.28 seconds for the light from the moon to reach the earth.
It takes approximately 8 minutes for the Sun's light to reach Earth.
The time taken by light to reach earth from moon is nearly about 1.29 seconds
8 minutes for the light of the sun to reach earth.
The Sun is the nearest star but it takes 2 hours to reach the earth. Correct answer is 8.5 minutes for light from the sun to reach the earth.
Just a bit over that; about 8 minutes 20 seconds for the Sun's light to reach the Earth.
It takes about 81/3 minutes for the sun's light to reach us on earth.
It takes 8 minutes for light from the sun to reach the Earth.
At the speed of light, a photon will take about 8.3 minutes (500 seconds) to reach Earth
It took light from the farthest observed galaxy about 13 billion years to reach Earth.
It takes about 5 minutes for the suns light to reach the earth
It takes light from the Sun about 8.3 minutes to reach the Moon, and it takes another 1.4 seconds for the light bouncing off the Moon to reach the Earth.
The moon does not emit light, rather it reflects it. The light from the sun shines on the moon, and it is reflected to earth.
It takes light about 25,000 years to reach earth from the nearest edge of the Milky Way.
Moonlight takes 1 min 3 seconds to reach earth.
Proxima centauri is located 4.24 light years away from the earth. What this means is that it takes light 4.24 years to reach proxima centauri from the earth.
Light travels at a constant speed. Therefore the farther away a star is, the longer it takes for light to reach us.
Ultraviolet rays do reach the Earth from the Sun. However, most of the UV light is blocked by the Earth's atmosphere and does not reach the surface.
