Eleven Light-Years Away, an Earth-Size Planet That May Be Habitable

Artist's rendition of what the red star looks like.

Who need's Elon Musk's Mars? There’s a new place that looks like it can sustain life.

An excerpt from the New York Times: Astronomers announced on Wednesday the discovery of an Earth-size planet around a small red star in our corner of the galaxy. The planet could hold liquid water and conditions favorable for life.

The star, Ross 128, is not the closest with a planet similar in size to ours. That would be the sun’s next door neighbor, Proxima Centauri, just 4.2 light-years away.

Ross 128, about 11 light-years from Earth, appears to be a quiet, well-behaved star, without the violent eruptions of radiation that might wipe out any beginnings of life before they had a chance to take hold on the planet.

Side question: What do you name the planet?

The key word being "may".  The reality is no one knows.

More pressing matters in relation to space expansion exist than just daydreaming.  Like getting a base on the moon (assuming we can even go there at all).

11 light years away. There is no way to get there except by generational ship and that would take centuries.  It would take a century just to get a results from the launch of a physical probe.

Cat Planet of course...

Cat Planet Cuties is the badly translated title ;-)

Oh I just remembered: their planet is called 'Catian' eh? We could call it that...

The only thing we need now is a way to travel at light speed, and then it'll only take us 11 years to get there.  It's doable.  I mean, if a non-sentient photon can figure out how to do it, surely we sentient human beings can figure it out.  We may not all be smarter than a 5th grader, but at least half of us have got to be smarter than a photon.

skeeter01 It would take longer: 1G acceleration for half the journey, then 1G de-acceleration for the second half. Time being relative the ship's crew wouldn't experience that, it would seem much shorter to them.

We'd need to send several un-manned probes first, in case they breakdown or don't work, have to send a bunch! The news would take 11 years to come back also... so maybe 30 years after probe launches to even find out if it's remotely habitable... assuming we have 1G ships (even probes!) with 11 years of fuel...

5cats when you put it like that, maybe it's not so doable after all... not with current technology, anyway.

skeeter01 Probes are much more feasible actually, and faster too. I forgot they can have lots of Gs in their acceleration eh? But that uses fuel faster so it's kind of a wash... the human-manned ships would be limited to 1G though, maybe a fraction higher.

Still would take 11 years after the probes arrived to see if the place is possibly habitable. If we knew how to transmit information that far...

skeeter01 Except a photon can only travel at the speed of light.  You and I have options.

Yeah, I'm not sure we would want to live there but it could almost certainly support some form of life.

Cool. Only like 65,000,000,000,000 miles away.

If the star is a red dwarf then the planet most likely is tidally locked (IE one side is always facing the star)  to that star due to having to be very close to the star to get any decent amount of heat.  I mean could be habitable for sure, would make for some very interesting life, one side eternally night one side eternally day.

normalfreak2 my understanding from the announcement was that the planet orbits in less than 10 days, but the star rotates much, much slower.  So not tidally locked to each other, although I agree most likely the planet is tidally locked to the sun.
