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.

∙ 14y agoNeptune is about 30 AU (astronomic units) from the sun, The Earth, by definition is 1 and about 8 light minutes so Neptune is sometimes close to 240 light minutes or 40 light hours or
0.00456 light years from Earth (at certain times)

∙ 11y agoThe general formula used for speed problems is based on the definition of speed:
speed = distance / time
Solving for time:
time = distance / speed
So, it really depends on the speed at which you move. If you move at a speed very close to the speed of light (not possible with current technology), it would take slightly over a year to travel a light-year. If you travel at 1/100 of the speed of light - still not possible with current technology! (that would be 3000 km/sec, 10.8 million kilometers/hour) or - it would take 100 years.
In summary, to travel a distance of one light-year, for a spaceship with astronauts, is currently not possible AT ALL, but it might be possible some time in the future.

Neptune's average distance from the sun is 2,793 million miles.
When earth and Neptune are at their closest possible separation ... lined up on the
same side of the sun ... they're 2,700 million miles apart. That's 0.00046 light year.
(rounded)
When earth and Neptune are at their farthest possible separation ... lined up on opposite
sides of the sun ... they're 2,886 million miles apart. That's 0.00049 light year. (rounded)

Speed of light = 186,282 miles per second.
Time for light to cover Neptune's average distance from the sun =
(2,793,000,000 / 186,282) = 14,993 seconds = 4hours9minutes53seconds (rounded)

Neptune is 4.18 light hours from the Sun (or .00047684 light years).

∙ 10y agoIt takes light 250 minutes (a bit over 4 hours) to get from the sun to Neptune. That makes Neptune much less than 1 light year away. Not even a light day. About 0.000475 light years.

What unit would you use to describe the distance between the Earth and Neptune?
Light years
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 long does it take light to travel a distance of 2700 light years?
Well, it takes 2,700 years for light to travel that far. Anything travelling at half light-speed would take 5,400 years. At 1/4 light-speed, it would take 10,800 years.
How does the distance from the sun to Neptune compare to a light year?
The distance from the Sun to Neptune is 4,504,300,000 kms Light travels 9,460,730,472,580,800 kms a year So light would take just over four hours to get from the Sun to Neptune. Most of us have taken a 4-hour road trip. So imagine driving solidly for over four years. That's how long you'd have to travel for (at the speed of light) to get to the next star (Proxima Centauri).
How long in years would take to travel 57 trillion km in light years?
Light years is not a time, it is a distance. It takes light about 6.025 years to travel 57 trillion km. In other words, 57 trillion km = 6.025 light years.
How many Earth's years would it take for Neptune to travel around the Sun 12 times?
About 1977.48 years.
What unit would you use to describe the distance between the Earth and Neptune?
Light years
How old would you be if you were 12 earth years and you moved to neptune?
You would remain 12 (Earth) years old plus the time it took you to travel there.
How long does it take light to travel a distance of 2700 light years?
Well, it takes 2,700 years for light to travel that far. Anything travelling at half light-speed would take 5,400 years. At 1/4 light-speed, it would take 10,800 years.

How long will it take to travel to neptune at light speed?
Neptune orbits about 30 AU from the sun, which means it is anywhere from 29 to 31 AU from us depending on where Earth is in its orbit. It would take about 4 hours to travel 29 AU at the speed of light.
How do you calculate the amount of years it would take to travel using light years and the speed of light?
from the book
How long would it take for light to travel 14 billion light years?
14 Billion years
If you are thirteen and travel fourteen light years how old would you be?

How long would it take to travel 4 000 light years?
Like any distance, it depends on how fast you are going. At the speed of light it would take 4,000 years to travel that distance.
