Sorry, I don't remember why I decided to change it, but yes, it's back now.

Good points, I do agree that the HZ isn't a firm 'If you're not in here, you can't be warm' type thing, it's just a baseline, but having a planet with a temperature of 25 c, liquid water, and life, while it's well outside of the inner HZ is extremely unlikely, as is finding a planet well outside of the outer HZ (Probably more likely, but not much) with an average temperature of 25 c. What a Superhabitable planet has, is that it's inside of the HZ, it's not guaranteed to have warm temperatures, liquid water, and life, yes, but it's a good start, and it's much more likely than a planet too close or too far from it's parent star. There are a lot of restrictions for planets too close and too far from their parent stars' to have "Just right" everything's, so it's extremely unlikely that we'll find a Superhabitable planet out where Jupiter or Mercury is for example.

Maybe, Although, it could just be someone asking a question, Who knows? Maybe someone should report just to be safe.

If we're talking about planets more habitable than Earth, it'll need to be in the HZ because of light, and temperature, if we're too close, we might survive but the temperature would be much higher than Earths, and it wouldn't be considered 'Superhabitable' and if it's too cold, we would need extremely good habitat modules for heat and extremely good clothes, and it wouldn't be considered 'Superhabitable". if a planet has 2x the Earths mass, the gravity would be 30% higher than Earths, and yes, it would trap more gases, but depending on where it's at in the HZ, it might be just right.

Kepler 442b is 1200 ly away, so no, not anytime soon, but GJ 667cf (Which, unfortunately is unconfirmed) is 24 ly away, so we should in the next 20 years.

Could you guys help support him? Crowdfund Site

Higher mass/brighter M dwarfs (Like Lalande 21185) would be big enough that planets in the HZ would have minimum orbital periods of 50 days, and maximum orbital periods of 140 days (Look at Kepler 186f) Which could be the lower limit (I'm guessing here!) for planets around red dwarfs to have day/night cycles without much help. Planets in the middle of the HZ would stay in it longer as the star ages and brightens. I know, but that's the characteristics of a Superhabitable planet. The higher gravity would spread the water around more.

Did you report it? That's what I do.

Quote from the wiki article: The average depth of the oceans also affect the habitability of a planet. The shallow areas of the sea, given the amount of light they receive, usually more comfortable for aquatic species, so it is likely that exoplanets with a lower average depth more suitable for life. The more massive than Earth exoplanets tend to have a more regular surface effect of gravity, which can mean a shallower ocean basins. On the other hand, the planets with less water than Earth are less likely to present a greenhouse wild if they are in the inner ends of the habitable zone and is less likely suffering from a global glaciation if they belong to the external border. Reference

So Superhabitable planets are planets that are more Earth-like than Earth, their characteristics are: They orbit either a M or K type star (For their long life's) They have a mass about 2 Earths (Because more shallow oceans from stronger gravity means more biodiversity, plus it's the ideal size for plate tectonics) They're near the center of the habitable zone (So they're in the habitable zone longer as their parent star ages) They have a temperature of 25 c (The ideal temperature for plant life as we know it) Looking at all of these, Kepler 442b and GJ 667cf may be candidates for being a Superhabitable planet because they fill in 3 out of 4 requirements, I bet you could figure out the one they haven't met Also, overall, they'll last much longer too, their parent star will last much longer than the Sun, giving the planet a lot of time to have life evolve, and the planet's size means it can protect itself from solar/cosmic radiation much longer than a Earth-sized planet can, which is also a big plus. So what do you guys think about the possibility's of Superhabitable planets?

Well... I'm gonna try to watch it when my dad gets back later this year. My mom probably won't say yes. Lets get back on topic.

Seriously? I haven't seen the show though, maybe the first minute a few years ago, but my dad told me that I wasn't allowed to watch it

First I would make a massive solar farm capable of lasting for 200 years w/o maintenance, then I would try to figure out how to make frozen embryos/robots to take care of them/teach them everything they need to know about making/creating stuff, then I would figure out cryostasis, freeze myself for 2500 years, and hopefully wake up to a technologically advanced civilization that could take me to space, where I'd spend the rest of my life zipping across the solar system

That looks amazing, awesome job

Well, Kepler 186 and Wolf 1061 are two, then there's GJ 180, Kepler 62, Kepler 296, and (Possibly, because none of them are confirmed, but there's 2 HZ planets) Tau Ceti.

That's a great idea, what system do you plan to use? Wolf 1061? Kepler 186?

Oh man! Fust looks EXACTLY as I imagined it! Props to you:D

1 The Bussard ramjet would have to be MASSIVE, also, due to 'drag' from hydrogen particles it wouldn't be able to get to those 99% c speeds. 2 Cryostasis doesn't work for me because I want the crew to be awake, meaning it's likely going to be a generation ship

Diameter 45m Length 100m Oh:/ sigh I guess Anti-Matter won't work very well, back to the Medusa I guess.

I'm okay with it being less efficient, as long as it gets to its target speed and is capable of slowing down. So 25000 tonnes to be safe, but that's just the antimatter needed, the spacecraft is 7500 tonnes, so roughly 32500 tonnes. So would a Photonic rocket get to the target speed? And how long would it take to collect the Anti-Matter from Jupiter?

100 people in each cylinder (There are two).

RIP Edgar, you will be missed. Will any Apollo Astronauts see people walk on Mars at this point? At least half of them have died now (The ones who walked on the Moon anyway), and it's at least 10-20 years until we walk on Mars. Would now be a good time to petition the gov't to triple NASA's budget, and have 60% going towards the SLS and Orion?

Rep to you if I had any.

.8Gs? Where did you get that number? Also, a planet with .8Gs would be a terran, not a subterran, it would be on the edge between the two however.

The Starship is being designed/built during an apocalypse, so an O'Neil cylinder won't be vital, instead, I'm thinking of a roomier submarine type spacecraft (Yes, for 33 years, I'm not crazy, read Ark) It'll be a lifting body aircraft and use retrorockets to slow down and skids to land.
