About how long will it take to travel a trillion miles in todays most advance spaceship?

Question

i know that a trillion miles is 1/6 of the distance light can travel in a year. But we clearly don't have any rockets that can travel 300,000km per second...so with what we do have right now, how long will it take for a spaceship (carrying humans) to travel a trillion miles?

(i'm unaware of the fastest spaceship unavailable at the moment)

Thanks to everyone who answered!

But wow...4000+ years just to reach 1/6 of a light year. We seriously could use an extension in the number of years in our life. Haha.

Answer 1

Speed of the Voyager space probes which have currently left our solar system is about 25, 000 miles per hour

speed = 25,000 miles per hour
distance = 1,000,000,000,000 miles

Time=(1,000,000,000,000 miles) / (25,000 miles per hour)

Time = 40,000,000 hours

Time =40,000,000 / 24 = 1,666,666.67 days

Time =1,666,666.67 / 365 = 4,566.21005 years

Answer 2

The fastest space ships we have at this moment (do not include the Mars Mission or the up coming Lunar Mission - those space ships are not built yet) travel between
25,000 and 50,000 Miles Per Hour.

1.000,000,000,000 Miles
Divided by
25,000 Miles per hour
=
40,000,000 Hours
or
1,666,666 Days
or
4,566 Years

Traveling at 50,000 Miles Per Hour,
the time would be half as much or

20,000,000 Hours
or
833,333 days
or
2,283 Years

Answer 3

Well, the voyager probes launched back in the 60s or 70s have only gotten like a billion or so miles out from Earth(estimating). But using today's technology, we could probably catch up to the voyager probes in say a decade if we gave it all we had. You have to remember that there is not any oxygen in space to burn, so we have to use other forms of propulsion that do not require O2.

What we could (or even should) do is create a huge rail gun out in space, and magnetically propel satellites out to where we need them around other planets and such. It would use MUCH less fuel to get them there probably due to having virtually no friction or resistance to motion when out in space.

Voyager II, launched in August 1997, is currently the fastest man-made object. Voyager II was still capable of sending data back to earth after recently punching through the heliopause (the boundary of our Solar System). Speed was calculated at 700 kilometers per second. And, it took ten years to accelerate from 166,000 mph -- geo-stationary earth orbit, or 1500 meters per second.

Answer 5

The fastest space craft ever is the New Horizons unmanned space craft now on its way to Pluto. In a few years is will pass Pluto at 27,000 MPH, which is 7.5 miles per second. At that speed it would take 4,228 years to go one trillion miles.

Answer 6

gg is correct. We have no technology that would allow humans to travel a trillion miles. Not even close. The fuel requirements would probably be in the millions of supertankers range.

Answer 7

The fastest know spacecraft to man is Voyager 1, traveling at around 17.4 km/s, converted to mph is 37800.

A trillion divided by 37800 = 26455026.4455 hours or 3019 years

Answer 8

We can accelerate small probes to about 25km/s. We could probably reach close to 100km/s two generations of ion drives down the road when we couple them to a thermionic generators or small nuclear reactors.

So that's 10^12miles/60miles/s=528 years.

Bon Voyage!

Answer 9

I am sorry to cut the conversation short, but the amount of fuel needed to travel that fast would be so immense. It doesn't exist, and would weigh down any craft so much that it would never leave the earth.
