## Can we travel 10 light years?

The short answer is that you would travel 10 light years in distance, it would take no time at all for yourself, but ten years would pass for others.

## Can we travel 3000 light years?

Traveling at light speed, it would take 3,000 years to get there. Or 28 billion years, going 60 mph.

## How many Earth years is a Lightyear?

A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km). One light year is equal to the distance that light travels in one year (it is about ten trillion kilometers, or six trillion miles). One light years is equal to approx 6.5×10^5 earht s years.

## How far is Earth in light years?

A light-year is the distance a beam of light travels in a single Earth year, which equates to approximately 6 trillion miles (9.7 trillion kilometers).

## How long is 40 light years in human years?

It would take only about 1.08 million years. This is by not taking into account that the distance in not accurate and hence can vary by several thousand years. It’s quite simple to calculate actually. You can just convert the distance from light years to miles and divide the distance by velocity.

## How far away is Voyager 1 in light years?

Slight different working. 8760 hours in a year and Voyager 1 is 19.4 hours away. so its 1/451.5 of a LY away. It’s taken 40 years to get there so 40 X 451.5 = 18,000 years ish and its slowing down so round it up to 20,000 years.

THIS IS IMPRESSING:  Best answer: Do tourists have to pay tax in America?

## Can we travel at the speed of light?

No, we cannot travel at the speed of light. … Consider this… the speed of light is 300,000 kilometers per second (186,000 miles per second) and when an object moves at this speed, its mass will become infinite. Therefore, infinite energy will be required to move the object, which is impractical.

## How far is Sun from Earth in light speed?

The Sun is at an average distance of about 93,000,000 miles (150 million kilometers) away from Earth. It is so far away that light from the Sun, traveling at a speed of 186,000 miles (300,000 kilometers) per second, takes about 8 minutes to reach us.
