# Question: How long would it take humans to travel 4 light years?

Contents

Apollo-10 (a lunar orbit mission) reached the highest speed ever recorded for a manned vehicle, at 24,791 mph. Moving four light years at the speed of Apollo-10 would take 107,300 years.

## How long will it take you to travel 4 light years?

Last year, astronomers raised the possibility that our nearest neighbor, Proxima Centauri, has several potentially habitable exoplanets that could fit the bill. Proxima Centauri is 4.2 light-years from Earth, a distance that would take about 6,300 years to travel using current technology.

## How long would it take to travel 1 Lightyear?

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 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 long would it take to travel 93 billion light years?

How many years it takes light to travel x distance. It would take light 93 billion years to go 93 billion light years. But the universe will expand more during that time. The visible part of the universe is 93 ly in diameter.

## 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.

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

The \$720 million New Horizons mission launched in January 2006, speeding away from Earth at a record-breaking 36,400 mph (58,580 km/h). Even at that blistering pace, it still took the probe 9.5 years to reach Pluto, which was about 3 billion miles (5 billion km) from Earth on the day of the flyby.

## Is warp speed possible?

“None of the physically conceivable warp drives can accelerate to speeds faster than light,” Bobrick says. That is because you would require matter capable of being ejected at speeds faster than light—but no known particles can travel that fast.

## Can humans survive the speed of light?

So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. … So, light-speed travel and faster-than-light travel are physical impossibilities, especially for anything with mass, such as spacecraft and humans.

## How long would it take us to get to Jupiter?

The distance between Earth and Jupiter depends on the orbits of each planet but can reach more than 600 million miles. Depending on what the missions do and where they go, it can take around two years to six years to reach Jupiter.

## How long would it take to get to nearest star?

Travel Time

It is traveling away from the Sun at a rate of 17.3 km/s. If Voyager were to travel to Proxima Centauri, at this rate, it would take over 73,000 years to arrive. If we could travel at the speed of light, an impossibility due to Special Relativity, it would still take 4.22 years to arrive!

## What distance is 1 light year closest to?

A light-year is a measurement of distance and not time (as the name might imply). 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 far in space can we see?

The farthest that Hubble has seen so far is about 10-15 billion light-years away. The farthest area looked at is called the Hubble Deep Field.

## How long would it take to get to the Andromeda Galaxy?

Although it may be one of the closest galaxies to our own, since the Andromeda Galaxy is 2.5 million light years distant it would take 2.5 million years to get there if (and it’s a huge ‘if’) we could travel at the speed of light.

## How long would it take you to cross the universe?

It’s Space Day, but traveling the vast entity that is space would take far longer than a single day. The nearest galaxy: 749,000,000 (that’s 749 million) years. The end of the known universe: 225,000,000,000,000 years (that’s 225 trillion) years.
