I definitely way jumped the gun in asking this question. I clearly did not have nearly the math and science background on any of this coming in. This isn't the kind of sci-fi that I am normally into. In addition to the fact that I really love to write parody and comedy, I'm more of a fantasy, time travel, paradox, or alternate reality type of writer. I have never in 25 years went to another planet in my writing. I've written lots of stuff over the years, even some alien stuff, but nothing like this. I actually thought this was going to be an easy question. Easy enough to maybe not even even ask it. I definitely did not know, when I picked Kepler-22b from a list of planets, that this was kind of a famous planet in the Astronomy world. This is why I was so cavalier in my first post. I thought this was a simple math question.
Quoted from bobmathuse:
OK, people, calm down. There's a terminology gap here. NASA refers to exoplanets' sizes in terms of multiples of earth's RADIUS, not VOLUME. That means you have to use the 2.4 times radius logic, not volume, so the exoplanet's surface area would be 2.4^2 times that of earth, i.e. a multiple of 5.76.
The reason NASA does it this way is that most people have difficulty understanding what "twice the size" means when construed as volume. If you were asked to create a ball "twice the size of a baseball" using volume, you'd struggle with it. Twice the size using radius you'd just measure and go.
As for the application here, a lot of science fiction writers have written about "world building", plus there have been hundreds of panels on it at conventions in the past 80 years (I attended a large number of these). Have you used any of those resources? Take a look at Murasaki or Medea for starters.
Of course for real surface area, try Ringworld (Larry Niven) or a Dyson Sphere.
Thanks for the help. I'm definitely not thinking I'm discovering fire or anything. At the end of the day, as of right now, this story on this world is more character and story driven. To me this is more of just a large Earth, but with interesting idiosyncrasies. Definitely not dystopian or even environment driven per se. The world should be the sauce, not the steak. I see my conflict in this fourth or fifth book as more of a new world land grab by competing factions as told by youths with issues, as it is YA. I'm definitely not thinking anything on the scope of a Ringworld.
Does Murasaki or Medea mean to look into "The Tale of Genji"? That's what I found. The Tale of Genji does seem worth reading about.
Quoted from Eightball88:
You could address the gravity issue by making the bigger planet only a bit more massive than Earth (ie, less dense) to account for the greater distance from the surface to the center of gravity. Don’t ask me to do the math, though
At the end of the day, I'm terraforming the whole thing from a water world into a large Earth, using rockets, nanobots, biologic packs, and a massive amount of BS. The whole thing is like just four paragraphs that have a tinge of plausibility, as long as it is humans doing this 300 years from now, more then us doing this today. I simply state it as fact, and then I walk away into the story. I'm honestly not worried a ton about it sounding 100% accurate at all. It just as to sound well thought out.
Think Matrix. You go, "That can't work!", but it sounds good and everyone just accepts it. It's like how does the Flux Capacitor work? Who knows. We get a crude drawing, and then 30 year later, there it is! Sometimes the less said, the better.
I just wanted it to have some "verifiable" stuff, because I know that Neil Degrasse Tyson ripped into "The Martian", and I figured if I could spend a few minutes having some "facts" in the book, then that was ok. I thought this post would be 3 comments deep at best.
Quoted from gonzo73:
Does gravity increase equally with more mass?
Or is there a curve.
If its equal, your human characters will need some sort of mech suit, or reinforced space suits.
Love syfy, keep us informed Captain.
Mission Kepler 22-B, day 1.
Hi. I love your enthusiasm, but this is more of a deep outline that you spend awhile thinking on. This series would span 1000 years from 10 years from now, to 3000AD, as it continues with the characters ancestors in a new time and setting. It goes current Earth, Future Earth, a planet in Alpha Centauri, spaceship, and then Kepler-22b. It's really not one of those books that you just start writing, and see where it goes. This is the type of series you plan, and plan, and plan, or it will suck, and suck, and suck.
I appreciate everyone's support, but this got a bit out of hand. I really thought this was a simple math problem. Although some of what people said, did get me thinking about new things I might not never have thought about, so that is really good. I mean this has not been, from my viewpoint, unproductive or anything.
I'm still not sure we have really got the right answer. Kepler-22b is apparently freaking huge compared to Earth
