# How Long Would It Take To Travel A Light Year With Current Technology?

Mankind’s speediest spacecraft so far is travelling 33,000 MPH.

At that rate it takes it roughly six hours to go as far as light light goes in one second.

That’s a ratio of one to 21,600.

So that means current technology could get us to our nearest neighbor two LY away in 43,000 years.

## How long would it take to travel a light year?

This duration is a bit of a problem, as it makes space exploration a painstakingly slow process. Even if we hopped aboard the space shuttle discovery, which can travel 5 miles a second, it would take us about 37,200 years to go one light-year.

## How fast can we travel in space with current technology?

For comparison, the Voyager 1 spacecraft, launched back in 1977, is currently traveling at about 38,000 mph (61,000 km/h), according to NASA — less than 10 percent of the Parker Solar Probe’s peak speed.

## Can humans travel a light year?

Interstellar distancesAs of January 25, 2020, Voyager 1, the farthest human-made object from Earth, is 148.7 AU away. Light in a vacuum travels around 300,000 kilometres (186,000 mi) per second, so 1 light-year is about 9.461×1012 kilometers (5.879 trillion miles) or 63,241 AU.

## Will we ever travel light speed?

Physicists generally believe faster-than-light travel is impossible. Relativistic time dilation allows a traveler to experience time more slowly, the closer their speed is to the speed of light. This apparent slowing becomes noticeable when velocities above 80% of the speed of light are attained.

## How fast is warp speed?

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.

## What is the fastest spacecraft we can build?

The fastest outward-bound spacecraft yet sent, Voyager 1, has covered 1/600 of a light-year in 30 years and is currently moving at 1/18,000 the speed of light. At this rate, a journey to Proxima Centauri would take 80,000 years.

## How fast is 20% the speed of light?

Traveling at around 20 percent the speed of light—so as fast as 100 million miles per hour—the craft and their tiny cameras would aim for the smallest but closest star in the system, Proxima Centari, and its planet Proxima b, 4.26 light-years from Earth.

## What is the fastest man made object?

1 Helios 2, 157078 miles per hourNASA Helios 2 space probe is the fastest man-made object ever.
