How many light years is Uranus to the earth?

Answer 1

Uranus is about 20 au (astronomical units) from the sun. Earth is 1 (which is the definition of astronomical unit), and 8.3 light minutes. 8.3 x 20 = 166 light minutes for Uranus. So when earth and Uranus are on the same side of the sun, the distance between them is minimized to 166 - 8 = 158 light minutes.

When Uranus is on the opposite side of the sun from earth, the distance is maximized to 166 + 8 = 174 light minutes. There is a bit more variation introduced by planetary aphelion and perihelion (the orbits are not perfect circles but ellipses).

The average distance is best described as the hypotenuse of a right triangle using those values: sqr(166^2 + 8^2), which is still about 166 light minutes.

Answer 2

Google to the rescue.

I typed 'distance from earth to Uranus' into Google and the first line answer was:

"Distance From Earth: At the closest point, 1,607,000,000 miles"

I then typed in '1,607,000,000 miles in light years' and the first line answer was:

1,607,000,000 miles = 0.000273369065 light years

Perhaps a more useful answer is to say it is about 2.4 light hours

Note that the maximum distance would be about 16 light minutes greater, or about 2.67 light hours. So the average is distance is about 2.5 light hours.

Answer 3

It is about 0.000332215362133935 light-years.

Uranus is not far enough away from the sun to be light years but you can measure it in astronomical units which is 150 million kilometres far every one (it is also the distance from earth to the sun) that would be 19.18 AUs.

Answer 4

The average distance from Uranus to Earth is about 1.8 billion miles, equivalent to approximately 19.2 astronomical units (AU) or 19.2 times the average distance from Earth to the Sun. In terms of light years, this distance is approximately 0.00031 light years.

Answer 5

The distance varies as Uranus orbits the sun; the minimum distance is 1.6 billion miles. This is equivalent to 0.000272 light years.

Answer 6

About 3 "light hours". It takes light from the sun 2 hours and 45 minutes to reach Uranus.

Answer 7

It is 0.00031861 light years away.
