## How long is a light-year in years?

For most space objects, we use light-years to describe their distance. A light-year is the distance light travels in one Earth year.

## How long would it take to travel 1 light years?

Saying we were a space shuttle that travelled five miles per second, given that the speed of light travels at 186,282 miles per second, it would take about 37,200 human years to travel one light year.

## How many light years is 365 days?

A light year is the distance light travels in one year (365 days). It often gets misused as a unit of time, likely because ‘year’ is right there in the name. It will always take light 1 year to travel a distance of 1 light year.

## How far can light travel?

## How fast can we travel in space?

## How long will it take to travel 20 light years?

The planet is so far away, spaceships travelling close to the speed of light would take 20 years to make the journey. If a rocket was one day able to travel at a tenth of the speed of light, it would take 200 years to make the journey.

## How long would it take to travel to Pluto?

Launched in 2006, New Horizons is the fastest spacecraft to ever leave Earth. It crossed the orbit of Jupiter the next year and has been traveling nearly a million miles a day—but it still took 9.5 years for the spacecraft to reach Pluto and its moons.

## What is light day?
