# How Long Would It Take Us To Travel One Light Year?

## How long would it take us to travel 31 light years?

There are 6 trillion miles in a light-year (approximately), so the distance we need to go is 6 trillion miles / light-year times 4 light-years, or 24 trillion miles. So, this trip would take 1.2 billion hours. There are 24 hours a day and 365.25 days per year, so this time in years is 137 thousand years.

## How long would it take to travel 100 light years at the speed of light?

Using one of the fastest space crafts ever developed, the Voyager 1 space probe, it would take roughly 1,736,809 years to travel 100 light years, travelling at its maximum velocity of 62,140 kph.

## Will we ever be able to travel at the speed of light?

As objects move faster and closer to the speed of light, they gain mass. So no, you can’t travel at the speed of light. Nothing with any mass can, not even subatomic particles. Light has no mass, so in clear space it is always traveling at the “speed of light” by definition.

## How many Earth years is a Lightyear?

For most space objects, we use light-years to describe their distance. A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km).

## Whats the fastest thing in the universe?

Within the universe, light is the fastest things, light as no mass, things with no mass could reach light speed. A shadow is the next thing, which can travel faster than light.

Thus warp 9 corresponds to a speed of 900 billion kilometers per hour (= 250 million kilometers per second) or about 830 times the speed of light.
