So Voyager has reached the end of the Solar System. Incredible feat. I'm ashamed to admit it, but I don't know the answer to this. Doeas anyone know what the escape velocity to our solar system is? It seems to me, but because of the suns gravitational pull, voyager should become a comet and fall back toward the sun. I don't know what the speed it would need to break the sun's pull though.

Good question. How much of a pull can the sun have on the craft at that distance, though? The escape velocity from Earth is about 11 km/s. But obviously the gravitational pull is powerful.

8 Km/s
"Physics Class"
Well....
Since Voyager is so far away from the sun maybe the gravitational pull is not as strong as what it was to escape earth. Think of pluto,
Earth's got a barely grip on it as it flies way outside of all the other planets. BUT!
This is only my logic, I'm seriously only guessing.
Not on the 8 Km/s though.

According to info I received in physics class some ten year ago, Voyager will continue into the cosmos undisturbed. Eventually it will reach the Centauri system, at which point it might fall into one of the stars or set itself into a degrading orbit.

A truely amazing feat!!!
Also I would imagine that the further from the sun the less the gravitational pull, and eventually you reach a point where the solar winds from the sun are more powerful than the gravitational forces... Mind you I'm not an astrophysicist........

For all the space travel enthusiasts, it is interesting to note that Voyager 1 was launched from Earth in 1977, and it has now taken 27 years to reach the limit of our tiny little Solar System.
An astronaut sitting in that vessel will be 27 years older, as he passes Pluto, than when he first left the Earth.
Would anyone like to calculate how old he will be, (or how long he will have been dead), by the time he reaches our nearest Galaxy, Alpha Centauri...
...?
Cheers...
...!

Hi Hagar...
...!
..only if I can take Britney Spears along with me, and do a bit of breedin' on the way, so that all my resultant brood can also do a bit of inter-breedin', and maybe someone will be left to contact Alpha Centauri ATC for a successful landing sometime in the far distant future.....
....!
..or am I being a bit optimistic...?
LOL...!
Cheers.
Paul.....gettin' the after-shave on, ready for Britney..

That's fine but what about your amazing din-dins? ???
I don't think there would be room for your gas cooker or a local Sainsbury's to supply the provisions to cook on it. A man has to eat you know & considering what you have in mind you would need something substantial to keep your strength up. Eating mush out of a toothpaste tube for all those years wouldn't suit me.

Fozzer, do you mean our nearest planet?
If light travels at 186,262 miles per second, that would equal 5,877,981,691,200 miles per year. Multiply that times 4.3 (light years to Alpha Centauri) and you find our pilot must travel 25,275,321,272,160 (thats over 25 trillion miles)!
Now, Voyager has traveled 8.4 billion miles in 27 years. That comes out to 311,111,111 miles per year.
So, divide the distance to travel by the number of miles traveled per year and you get:
It would take our intrepid pilot 81,242.1 years to reach the planet Alpha Centauri! Better pack a lunch.
Just in case you meant the nearest galaxy you need to look at slightly larger numbers. Andromeda is 2,200,000 light years away. It takes our pilot 18893.6 years to travel one light year.
To travel to the nearest galaxy will take our boy 41,565,920,000 years. Better pack a BIG lunch!

I often refer to my "Readers Digest" map of the universe.
..and in doing so is it possible to comprehend the ENORMOUS distances involved.
The distances in "Light years", calculated in "recogniseable" time and "recogniseable" speed is more than the average human brain can comprehend....
...!
..and for that reason I don't think that many people realise quite what is involved in so called "SpaceTravel".
Me...?
Together with Patrick Moore, I think I do...!
LOL...!
Cheers...

P.S. I've always been fascinated with Voyager1's trip in space, I'm just very glad that I'm not on it...

Yes, very nicely done. Did you do all that or copy an article?
I might have missed, or am just too lazy to go back, could you translate how fast Voyager has been going for all these years?
I would guess 10-20000 MPH

I think it comes out to around 14,205 miles per hour... Take 311,111,111 miles per year, divide by 365, then divide by 24 gives you miles per hour...
