How long would it take to get to Uranus if traveling at the speed of light?

Answer 1

Minimum distance from Earth to Uranus: 2.582 x 1012 m

Speed of light: 3.00 x 108 m/s

d = vt

t = d/v

t = 2.582 x 1012 m/3.00 x 108 m/s

t = 8606.67 s = 2.39 hours

Answer 2

First of all, a light year is a measure of distance, not time. Second of all, a light year is a very long distance - it's literally the distance that light travels in a year. From Earth, Uranus is roughly 0.00027 light years away.

If you mean How long would it take to get to Uranus travelling at the speed of light?

The answer is zero seconds. Time does not elapse for the traveller when travelling at the speed of light due to relativistic effects. For an observer on Earth, it would be about 160 minutes.

Answer 3

Uranus orbits the sun at an average distance of about 2.877 billion km (19.2 AU).

So when Earth and Uranus are lined up on the same side of the sun, the distance is 18.2 AU,

and when they're lined up on opposite sides if the sun, the distance is 20.2 AU.

At the speed of light, the time ranges from 2hours 31.4minutes to 2hours 48.1minutes.

Answer 4

That would depend on where you're coming from. If you

start at the sun, it takes about 160 minutes.

(That's 2hours 40minutes.)

Answer 5

That would depend on where you're coming from. If you

started at the sun, it would take about 160 minutes.

(That's 2hours 40minutes.)

Answer 6

Assuming Earth and Uranus were aligned with the Sun, light would take about 2.5 hours to reach Uranus.
