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.
Neptune 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)
The 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.
Earth's average distance from the sun is 93 million miles.
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)
Neptune's average distance from the sun is 2.793 billion miles.
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)
Neptune is 4.18 light hours from the Sun (or .00047684 light years).
Traveling from Neptune to Earth would take about 4 light-hours, as light traveling at the speed of light takes about 4 hours to reach Earth from Neptune.
It 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?
The time it takes for light to travel from Earth to Neptune varies depending on the positions of the two planets in their orbits. On average, it takes light about 4 hours and 20 minutes to travel from Earth to Neptune.
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 far from Earth is Neptune in light-years?
Neptune is about 4.3 billion kilometers away from Earth on average. In light-years, this distance is around 0.000046 light-years.
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.
How many light years does it take to get from earth to neptune?
It takes about 4.3 light hours to travel from Earth to Neptune.
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 long does it take light to travel from earth to Neptune?
The time it takes for light to travel from Earth to Neptune varies depending on the positions of the two planets in their orbits. On average, it takes light about 4 hours and 20 minutes to travel from Earth to Neptune.
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 would it take to travel at the speed of light from Earth to Aldebaran?
It would take approximately 65 years to travel at the speed of light from Earth to Aldebaran, which is about 65 light-years away. However, currently, we do not have the technology to travel at the speed of light.
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?
30 years
How far from Earth is Neptune in light-years?
Neptune is about 4.3 billion kilometers away from Earth on average. In light-years, this distance is around 0.000046 light-years.
