Nasa confirmed that it detected a possible habitable planet in the solar system Kepler 22 600 light years away from us. It seems that this planet can sustain life as it maybe have water in the liquid form.

At this moment even if we travel at the speed of the fastest man made object, the Voyager it will take to much time to reach it.
Voyager travels at this moment at the speed of 18 m per second so just make the calculations.

It seems that space exploration to reach other planets will be the next challenge in the years to come, not only from the engineering and technological point of view, but also from the financial point of view, as building a space ship capable of taking humans to colonize other planets will not have any financial return, as it will take more than one generation to get there.

Any future space ship will have to travel faster than light to make any voyage possible, and this barrier it’s still under discussion with the neutrino experiments.

Just a thought, if Mankind finds a way of colonizing other planets in different solar systems we will extend the existence of our species for thousands of years.

18m per second? That is 64.8km per hour = speed of a car?

wikipedia said it is 17km per second.

Like 22 600 light years vs. 600 light years? (Perhaps I should have pushed the Reply-button instead?

Anyway, by reading through, it now has the name or designation Kepler 22 or Kepler 22 B. Therefore my confusion, perhaps.

I guess it is a star and a planet belonging to the star, revolving around it and perhaps having seasons because of its possible orbit or inclination in space as well as with its relation to the orbit around its star.

But why not A then (for the star), rather than B (for the planet, I guess)?

I have been thinking on it. we will not die with the sun. as we know, the sun will become a red giant after approx. 10 billion years. TEN BILLION YEARS! ahem, sorry. I think the first human on a so called "exoplanet" will be real in maybe 200-300 years, if we compare the 18th century and and our technical advancement today

There is probably just as much a chance that mankind will not survive as long as the planet given our tendencies toward self destruction.

but lol, even if we would travel as fast as light => 600 ly away = 20-30 generations lol (if each moms&dads have babys at every 30 to 20 years old ^^)

better to focus to all stars within 20 ly (even 10 ly)

secundo: bah we really still have to find the technology to do it:
warp, subsonic, subspace engines ^^ or worm holes ^^ or stargates ^^

Although 600 light-years is relatively nearby, it's still so far away that we'll never be able to do anything about it. All we'll have is the knowledge that there may be a habitable planet there. Eventually, the telescope technology will exist that will allow us to take a close look at it from here. We'll be looking at it how it looked 600 years ago, though.
