This week was rumbling with Kepler rumours, and today it was announced: First Exoplanet comfortably within a habitable zone discovered.

I call it Odin.

Apparently they don't know the age of the system, so it might be fresh and primitive, or sprawling with abstract, alien intelligence.

Assuming it is habitable, of course.

Yes, they have been recycling info on this planet for over an year now, and there's still no relevant info of wether or not life's possible there. No single hint.
Plus, if I remember correctly, it doesn't spin around itself resembling our moon, so the habitable zone would be somewhere fixated between the lightened and shadowed sides. It probably would suck to live in a planet where dawn or dusk lasts forever.

You're thinking of the Gliese system. Those planets are tidally locked to their sun like our moon because their close orbit with their small red dwarf star, so one side is in perpetual dark while the other is in daylight. But with an atmosphere above 1 bar it'll likely stabilize the temperatures across the planet, but there'll be strong storms. With a thin atmosphere, it would move to the dark side, freeze and fall as snow. So one side would be a dry near-vacuum and the other is a snowy, indescribably cold vacuum.

But it doesn't matter anyway, since the Gliese system only have planets dangerously within or without the habitable zone.

This planet is newly announced. It's fresh off the presses. It isn't tidally locked, and it has an orbit very similar to ours. The gravity is quite manageable. But right now we can only measure mass, size and the orbit. No surface details or atmosphere measurements, we need real deal space telescopes for that. So more concrete stuff will have to wait.

Maybe if the embarrasing James Webb telescope launches.

Force of gravity is given by F = G Mm/r²
We do know its size, 2.2 times the earth, but we DO NOT KNOW its composition. So we cannot predermine its density, and hence there's no way to figure out gravity value for now.
But i guess they'll start evaluating what it's made of with spectrometers soon. Let's wait for now!

No, no it's not.

It'll be hundred, maybe thousands of years until we visit other stars.

Most educated space fans and engineers actually seem to distance themselves from the idea that space colonization is inevitable, and especially that it'll happen in the near future.

Just because it might be a garden planet does not mean it is gonna be a picnic.

It might as well be an endless acid boiling sauna storm like Venus, or a gravitational nightmare, or a barren wasteland filled with poison.

So who the fuck cares. Go do research that benefits humanity. This is a waste of time.

make sure to have enough fuel to accelerate to a decent velocity and slow down using the same amount, and have some left over to move in the system if needed.
build it so that it's not too big to kill itsef with centrifugal force, sturdy enough to withstand an inevitable occasional hole by cosmic crap
make it a small ecosystem where life makes life and recycles itself, and only small amounts of material has to be stored away and added for what will be inevitably lost in time.
Power internal systems with starshine.

Here's some crappy math.

Neptune has a radius 3.8 times the size of Earth. It is made of gas, and has a mass of 17 Earths. The "surface" gravity is 1.14, which is perfectly manageable in centrifugal tests. Even if this planet is made of heavier silicate, the gravity would probably still be somewhere within this frame. The frame of reference for Super Earths is actually below 10 Earth masses, far below the mass of 1.14g Neptune.

So I think you'd be fine. But your kids might become stocky.

Incredibly wrong. It'd still take like 200 years given we can max out speed, and in the process the ship would be constantly bombarded by radiation. The spaceship would become a lifeless asteroid made of metal within a year. You can't make a stable ecosystem in space.

Super Earths are below 10 earth masses per definition. Neptune is 17, and its gravity is manageable.

I did some searches, though, and it all depends on how compact the planet itself is. It can range from comfortable and Earthlike, to losing consciousness because the blood pools in your feet.

except it will benefit humanity because once our resources are used up (and they are being used up at an incredible pace, too quick for them to be replenished) we will need somewhere to go. Otherwise all of humanity will simply die to our own stupidity of wasting our resources with out a single thought in our minds.
