The furthest star would be in the furthest galaxy. [See related question] That is about 12.9 billion light years from us - and probably accelerating away from us.
So light would take 12.9 billion years to reach us.
This is just the farthest galaxy we know of, considering the universe is bigger than what our cameras can pick up. Considering a common belief is that the universe is infinite.

Why is it important to know how long light takes to reach the Earth?
Since light travels at a known speed and changes in frequency as it travels, it provides a way of measuring the distance to faraway stellar objects (stars, galaxies). This provides important clues to the structure of the universe. To the naked eye, dim nearer objects (asteroids, planets, stars) look the same as bright faraway ones (galaxies). Some distant stars and galaxies whose light reaches the Earth today no longer exist, at least not in the form they had when the light was emitted, many millions of years ago. As for the light from the Sun, its 8-minute travel time to Earth is an interesting concept, but has little bearing on how the Sun affects the Earth.
Why do scientists use light years to describe the distance between Earth and other stars?
Because in normal units the numbers are too . . . astronomical. At 299,979 km per second, light travels 1 light year in one Julian year, 365.25 days. So quite a long distance. Earth is 8 light-seconds from the Sun, the nearest star is just over 4 light years away.
How long does it take for the light generated by the star Betelgeuse to reach Earth?
The light takes about 640 years to reach Earth, as Betelgeuse (a red supergiant star) is about 640 light years from Earth.
How long does it take for light years to travel around the earth once?
One light-year is the distance light travels in one year, which is about 5.88 trillion miles. Light doesn't orbit the Earth, but if you're asking how long it takes light to travel around the Earth's circumference once, at the speed of light (about 186,282 miles per second), it would take only about 0.13 seconds.
How long does the light of Antares reach us?
answer:The light of Antares reaches earth in 600 liht years.
How long has light from other stars been traveling toward earth?
Well it depends on what you mean. The distance for how long it takes, or the time as in how long since Earth was made. Earth as you know has been here a long long time. Stars light has been shinning towards Earth eversince it was made. To see how long it takes for a stars light to reach Earth depends on how distant and huge the star is.
Why do you see a star how it was?
You see a star as what it used to look like because the light from the stars takes so long to get to Earth. While the light it making its way to Earth the stars are burning out, some of the stars we can see may have been burnt out for millions of years now!
How long does it take stars light to get to us?
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 light to get to earth?
The light takes 8.19 mins (8 mins and 19 secs) to travel from our Sun to the Earth. Light from the stars can take years or billions of years depending on their position in the universe.
How long does it take for light from big dipper stars to reach earth?
The stars from the Big Dipper are approximately 80 light years away from Earth, meaning it takes 80 years for the light from those stars to reach us. This means that the light we see today from the Big Dipper actually left those stars 80 years ago.
What measurement do scientists use for the distance between stars and Earth?
scientists use light-years to measure long distances in space. a light year, (abrviated ly) is the distance light can travel.
How long does it take for light from other stars hits the earth?
From Toliman, it takes a little over 4 years. Other stars are farther away, so it takes still longer.
Why are the stars that you see in the sky now how they looked like thousands of years ago?
The light from stars takes a long time to reach us due to their immense distance from Earth. When we observe a star in the sky now, we are seeing the light that was emitted by that star thousands of years ago. This is because the speed of light is finite and the universe is vast.
Are some stars about as small as earth is?
Yes, there are some stars as small as earth. It depends, however, on where the stars are located and how long they have been burnt out.
How long does it take light to get to earth from most individual stars you see at night?
that question is impossible to answer without a specific star because they are all in completely different places. Most of the stars you can see as individual stars are less than a couple of thousand light years away. The nearest are just 4 light years away.
How long do the stars twinkle?
Stars will appear to twinkle for as long as Earth has an atmosphere, because it's the atmosphere that causes the effect. From space, they're a steady light. This is why we have the Hubble telescope in orbit. Less atmospheric inteference = more accurate images. The stars themselves will stop emitting light when they run out of fuel to burn. That will in most cases be several billion years.
How long does it take for light from stars to hi the earth?
The answer is different for every star, because every star is a different distance from the earth. Here are a few: -- From the Sun . . . 8minutes 20seconds -- From the nearest star outside the solar system . . . 4years 2months -- From the North Star . . . 430years -- From Sirius (brightest star in the sky except for the Sun) . . . 8years 7months
