New world awaits?

Perhaps a new world awaits us, at a mere 95 light years away...

Interesting, Earth orbits at the very fringe of the Sun's sphere.

I doubt that this means anything, it's still very far off.

Lets hope its not a mirror.

Erm. If you're reffering to the diagram, it says "1au", the distance between the sun and the Earth. All that yellow in the diagram, I assume, is heat and light from the sun showing us the habitable zone.

Yes, I know the earth doesn't skim the sun's surface, thank you.

Well, yet another juicy fruit waiting to be plucked by an increasingly sessile humanity. Go us.

Then I must've misunderstood what seemed to be a blatantly self-explanatory comment.

Please feel free to correct me.

New world nothing. This is completely useless and pointless information and
presuming it to be a "new world". The new world for us for the next million
years is this solar system and the near endless resources in it.

And that planet is not 'near jupiters orbit'. Firstly, its closer to Mars' orbit
then to Jupiters, and more accurately its nearest the Belt orbit which is,
roughly, 2.8au.

The system also isn't necessarilly like ours at all. Orbits of large Jovians are
not an indicator of the orbits of small Terrestrials. For all we know there
may be smaller terrestrials further out, and only dense Jovians nearer to
HD 70642.

I wouldn't have been grinning if I was that stupid...or maybe I would be.

Now that comment was confusing!

the habitable zone for a human is between venus and mars, both of which represent extremes for planet side living. Habitable space is anywhere in the universe, given technology. The requirements to get to another star system are also such that we could exist in interstellar space for a very long time before fuel runs out, which might also be never because you could use magnetic ramscoops.

The only benefit to finding other worlds outside the solar system would be to find jovians to use for He-3 fuel, which will be pointless since our gas giants would last 1 million fully modernised humanities for 5 billion years.

The main point of this search is not to extend humanity. It's to see if other (possibly sentient) life could have formed in other stellar systems.

Ofcourse it could have. You don't need planets in earthlike orbits for that to happen. But its irrelevant because until we discover signals or FTL we're never going to actually know. unless, ofcourse, we can build a telecope that will actually photograph another world thats been industrialised and we can zoom in and see things evidence of this.
