The time would be T= d/c where d is the distance between Earth and Neptune and c is the speed of light.

How long does it take light to travel from earth to Neptune?
Neptune has an average distance from the Sun of 2.8 billion miles and the earth is 0.09 billion miles from the sun so it is 2.71 billion miles from the earth. Light travels at 186,000 miles per second. So 2.71 x 109 divided by 186,000 = 14570 seconds = 4.05 hours = 4.62 x 10-4 years.
How far from Earth is Neptune in light-years?
It isn't even 1 light year. Its 243 light minutes.
What unit would you use to describe the distance between the Earth and Neptune?
Light years
Why is the distace between earth and the sun measured in light minutes and the distance between neptune and the sun measured in light hours?
Because it only takes 8 minutes for sunlight to reach Earth, but it takes 4 hours to reach Neptune.
How long would it take to travel from Neptune in light years?
The average distance from the Sun to Uranus is 2.88 billion km. The distance from the Earth to Uranus would vary depending upon if our planet is on the near side of the Sun from Uranus or the far side. If we take the average distance of the Sun to Uranus as a neutral point, and the speed of light is 300,000 km/sec --- (2.88 billion km) / (300,000 km/sec) = 9600 light sec, or about 160 light min, much, much less than a light year. In other words, traveling at the speed of light, it would only take about 2 1/2 hrs to get to Uranus. Light years are a term usually reserved for great distances, such as the distance between stars.

Could you see with the little sunlight on neptune?
Yes. The sunlight on Neptune is less than that on Earth, but brighter than the light of a full moon.
Why is it important to us on Earth that light can travel through space?
It is because light can travel through space that Earth can get sunlight. Without sunlight life on Earth could not exist.
Light to travel from sun to earth?
It takes approximatly 7minutes to travel from sun to earth the sun light.
What are the waves that travel from the sun to earth?
Light waves travel from sun to the earth.
What is the speed of Neptune from earth not at light speed?
Try again, this is very unclear
How many time does light travel around the earth in one second?
light can travel around earth about seven times
What does light travel as to get from the sun to earth?
As light, of course.
How far from Earth is Neptune in light-years?
It isn't even 1 light year. Its 243 light minutes.
How fast would it take to travel to Neptune at light speed?
it would take about 12 weeks
Why do light waves require a medium in which to travel?
Light waves do not require a medium through which to travel. They will travel (propagate) perfectly well in a vacuum. Otherwise, light would not pass through the vacuum of space. It would be very dark here on earth as the light from the sun, moon and stars could not reach Earth through the vacuum of space.
How long does light from the sun to travel to earth?
Light take approximately 8 minute 20 seconds to travel from the sun to the earth.
