How long will it take to travel to neptune at light speed?

Answer 1

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.

Answer 2

Depends where your departure point is and where Neptune is at the point of launch - and a few other technical considerations.

A best guess, forgetting acceleration, deceleration - not forgetting how you would achieve this - is about 0.0005 light years

Answer 3

At its closest, Neptune is 2,771,162,074 miles from Earth. At 18,000 miles per hour the trip would take at least 17.56 years.

Answer 4

I have no idea. You have asked the wrong person. But I would have to guess maybe 3-4 days. I tried my very best!!!

Answer 5

The trip would take a minimum of 18 years at 17,500 mph

Answer 6

It would depend on the launch date, since the trajectory would vary widely.

Answer 7

4 hours and 20 minutes.

Answer 8

380 light years

Answer 9

1

Answer 10

375 days
