It's all about density. A planet can be seven times bigger, but if it's density remained the same as Earth's the gravity might not change all that much, because the surface farther from the center of mass.
 
2012-11-08 01:13:06 PM  
For example, Saturn has many times the mass of Earth, and is vastly larger, but if you could stand on the "surface" the gravity you would experience is only about 0.9G
 
2012-11-08 01:17:12 PM  
Sorry for the multiple posts, but I love this stuff. Saturn is kind of cool in that there are probably places in the atmosphere where the pressure and temperature are very close to that of Earth, although the atmospheric composition would be quite different. Theoretically you could build floating habitats that all you would really need to provide is air, which is a great deal easier than dealing with vacuum or extremely cold or hot environments.

That sounds about right. Last time I ran the numbers, the fastest proposed propulsion system currently under serious study would go 20 light years in about 47,000 years. So if we throw in a bit of semi-plausible sci-fi, we might be able to get the one-way trip to this place under 100,000 years.

Project Daedalus estimated top speed of 10-12% c. or around 400 years. Long enough so that the travelers would probably be passed by faster technologies on the way out.

If only there were some kind of density thingy and mass thingy which could be used to calculate the gravity.

7 times as large is not the same as 7 times the mass.

Overall its radius is between 1.9 and 2.5 that of Earth's radius and 7 times as massive, at least on some calculations. Depending on the density of the planet and its size, it could actually have the same surface gravity as the Earth, meaning if you stood on HD 40307G you would weigh the same as here on Earth.

In this case it is, they don't know its size only its mass, and I don't think a planet of that mass could maintain a low enough density for human habitation.

Still part of what makes earth habitable is that it has a magnetic field that shields us from radiation. If the planet lacks density then it probably doesn't have the iron core that generates the magnetic field we enjoy. But who knows maybe the intensity of the star it's orbiting isn't that of our own sun so it can support life with less of a magnetic field.

It also may not be unfeasible that we could withstand 7 times the gravity. You'd of course suffer joint problems but smaller lighter stronger individuals would have an advantage; possibly causing adaptation of the species to occur after a few generations.
 
2012-11-08 04:59:44 PM  
If we assume the composition is roughly Earth-like, then 7 times the mass means a radius 1.913 times that of Earth (cube root of 7). Gravity decreases by the square of distance, so being 1.913 times further away translates into a multiplier of 1/(1.9132), or 0.2733. Multiply that by the 7 masses and you get 1.913 gravities.

Which would have been a lot simplier if I'd just looked up the Wikipedia article on surface gravity: ...for fixed mean density, the surface gravity g is proportional to the radius r.
 
2012-11-08 05:01:01 PM  
Lots of mights and could be's in that article. I'm surprised they didn't say how long it's day is, or how much water is in its oceans. You know, if there's really even a planet there.

Now that we have it, we are scanning star systems faster than human eyes can interpret the data. According to wikipedia, as of today, there are 846 known exoplanets. As of February of this year, there were 2,321 possible candidates still to be examined. It seems like more are added every week.

And from that sliver of possible data, writers generate these fantastical claims of planets with liquid water, livable temperatures, correct gravity, etc.


They don't actually know any of this. They don't even have much reason to suspect any of it. Just like every other prediction of planets light years away. They've got some radio waves. That's it.

These articles drive me nuts. There's more to making a planet habitable to humans than being in the Goldilock Zone. and being a rocky planet. The size of the planet also matters. Too big and it's gravity will not allow for mountains high enough to make land masses and you'll effectively have a water world, too small and it won't be able to maintain an atmosphere and surface water (think Mars). If a planet has 7 times the mass of Earth then it won't matter that it's in the Goldilock Zone and it won't matter that its a rocky planet. We can't live on it.

midigod: SacriliciousBeerSwiller: They don't even know it's not a freaking gas-ball. The "super earth" speculation seems to serve no purpose but to get people to pay attention to what would otherwise be fairly mundane.

A few years ago the tech to discover exoplanets didn't even exist, and now it's just "mundane?"

Holy shiat.

/no words


Yeah, people get jaded quick here in the future.

Imagine a $20 used iPhome. Today, it would be laughably bad, bought mainly for the "wow a knockoff" kitch factor and not taken seriously.

Send it back to, oh, 2002. "OMG DUUUUUUDES LOOK AT THIS OMG OMG LOOK WHAT IT CAN DO"

Hey neat, and only 42 light-years away! That means we should be able to get human colonists there--let's see now--oh, right ... never?

Double the radius is 4 times the surface area.

Something like 800million square miles!

NowhereMon: Elzar: 7 times as large as the earth - I don't think you fools understand the gravity of this situation...

It's all about density. A planet can be seven times bigger, but if it's density remained the same as Earth's the gravity might not change all that much, because the surface farther from the center of mass.


yes and that's exactly the problem with earth: too many stupid people.

2words1finger: whargbble Cosmology is nothing but a sunk cost. Paying for a bunch of pasty nerds to stare at the stars and fantasize about a bunch of Star Trek bullshiat serves no practical purpose for humanity. I seriously do not understand why we waste money on stuff like this.


we will extinguish ourselves and everything around us here on earth before the possibility of that 42 light year trip would be economically feasible .....unless we build starships that run on landfill, nuclear waste and stupidity.

then it's just a few minutes away and not long until anything and everything on that planet is wrecked , raped and ruined..then, fill 'er up on twinkies, episodes of Guns and Jugs, have an election or two and WHOOSH!; time to poison up another atmosphere somewhere else..

just remember kids: throw that litter out your window and don't worry, it's not your problem.

NowhereMon: kimwim: So with our present technology, solar sails, radiaoactivaty, the whole thing: how many generations would it take us to get there?

Project Daedalus estimated top speed of 10-12% c. or around 400 years. Long enough so that the travelers would probably be passed by faster technologies on the way out.


Yeah, this is what I was thinking. Why send a ship with current technology that's only going to get passed eventually by better technology. Starting first doesn't mean you're going to win the race.

I wonder if there's anyone that believes the government secretly has the technology to go near/past the speed of light, but simply doesn't?

Fano: Yeah but then you need to get Orakio's Sword to defeat Dark Force that is buried in the lake temple on your generation ship.


And Laya's Bow and Miun's Claw and Wren's....

Why the fark am I talking about PSIII on Fark?!?

2words1finger: Seeing as that we currently can't get humans any farther out into space than a couple hundred miles, I don't really see the point. It's not like we're ever going to get to this planet, so who cares? All the money they're spending on BS programs like this could be put to much better use developing useful technologies like sustainable energy or better farming techniques to help feed the hundreds of millions of starving people in the world. Cosmology is nothing but a sunk cost. Paying for a bunch of pasty nerds to stare at the stars and fantasize about a bunch of Star Trek bullshiat serves no practical purpose for humanity. I seriously do not understand why we waste money on stuff like this.


old and busted: trolling the geek tab with religion bashing. New hotness: trolling the geek tab with astronomy bashing.

Ok cool. So now all we need is a diplomat, scientist, a green moment zealot, a religious nutcase, a dictator type and a hard core capitalist.

Let's do this.

Load 'em up on the "B" ark and prepare for launch.

Such a planet would be made out of stuff so light it would be useless to us.

Like water?


Like no heavy metals.

Gravity doesn't work that way, you know.

Only 42 light-years away? So long and thanks for all the fish!
