Could you verify that all the temperate planets in New Eden are actually in the Goldilocks zone?
This is messing with my immersion.

Why do they have to be?
You would need to cite the spectral class of the star or stars in the system you wish to survey.

The way you usually calculate this zone is somewhat simple actually! Since every star in EVE provides the necessary info! =D
We do it in a few steps
Ri = Sqrt( Lstar / 1.1 )
and then
Ro = Sqrt( Lstar / 0.53 )
where Ri = the inner boundary of the habitable zone in astronomical units (AU), and Ro is the same but the outer boundary.
Lstar is the absolute luminosity of the star. 1.1 is a constant value representing stellar flux at the inner radius, and 0.53 like above represents the outer part.
So just click info on any given star and calculate away!
For example, the sun in the 6-CZ49 system in EVE the sun has a Luminosity of 0.14, which means:
Ri = Sqrt( 0.14 / 1.1 ) which equals to an inner habitable zone radius of 0.35 AU from the star, and then
Ro = Sqrt( 0.14 / 0.53 ) which equals to an outer habitable zone radius of 0.5 AU from the star.
To prove these calculations, input the same info using our very own star and you will get a delightful confirmation that the earth is indeed within the Goldilocks zone.
Furthermore there are other determinating factors. Such as the atmosphere of said temperate planet. If the atmosphere is several times thicker than the Earths atmosphere it would have a big greenhouse effect thus causing the temperature to be within the liquid water range.
Also nuclear decay from the planet itself would cause sufficient background radiation to support liquid water and an atmosphere.
Point being it IS possible for a planet to be outside the Goldilocks zone and still be habitable. |

Eve planets are all over the place. Ice planets where there can be no ice, temperate planets in wild locations. Sure there can be "special cases" but in eve most every system is "Special".
Also there are issues like the star in Luminaire is 30 billion years old. Which is sort of hard to have in a 13.7 billion year old universe. And no, its not clue to something odd. When I was in the AJ project I checked with CCP Dropbear. Its just a mistake.

It's almost like it's a computer game where you're supposed to enjoy shooting things, and not worry about the scientific accuracy... Next up you'll be asking CCP to prove the biomechancial mechanism and software that allows the implants to interface with the human brain. |

The real question is...
Is it possible for that planet to be closer to the sun than the GZ and still be habitable?

It would be hard (on high luminosity stars it could be easier, on low ones alot harder due to the tidal lock that will happen at such short distances), but considering what freaky exoplanets we discover every other week, I wouldn't rule it out.

Well let's just say it's not impossible, just very very, very unlikely. Look at Venus for example, there's signs it may have had water in the past, but it's atmosphere, consisting of 96% or something CO2 is basically a greenhouse effect gone out of control causing the temperature to evaporate all the water.
So "habitable" is all relative. Perhaps habitable for micro organisms living deep inside the crust or something. |

This is a solid discussion, but I posted this like 8 hours ago, and CCP still hasn't fixed this "issue".
Now I want the Ice planets on the backend of the GZ.

It's easier for a planet to warm itself up than cool itself off.
For example, one of the moons of Jupiter is thought to have liquid water under it's icy surface that could sustain life.

Considering planets don't actually orbit and that many stars are impossibly old (like hundreds of billions of years) I wouldn't count on them having that kind of attention to detail.

Yep, that would be Europa.
Venus is also much, much hotter than Mercury owing to its extremely thick and CO2 rich atmosphere, despite Mercury being much closer to the sun.

I was under the impression that Venus's atmosphere was more H2SO4 than CO2. I could be wrong.
CO2 is not the only greenhouse gas, it is just that on Earth it is the one that has had the most change on our climate. Methane is significantly more active as a greenhouse gas, for instance.
Back on the original question, a planet with a highly reflective atmosphere could probably exist inside the inner boundary of the Goldilocks zone while still being inhabitable for human life. Consider how Earth has had phases of 'nuclear winter' caused by volcanic eruptions - a planet that was seismically active enough to have constant volcanic eruptions might have nuclear winters most of the time and could thus have a temperature under 50 celcius (122 F) constantly. It may even have polar ice caps. Such a planet would need an ecosystem that could absorb all of the sulfur that volcanoes tend to vomit out but perhaps bacteria (or some form of life with no Earth analogue) exist on it that can do just that.
Furthermore, a planet inside the Goldilocks inner boundary might be habitable near the poles but have an unsurvivable equator.

That doesn't mean that sci-fi (or any other setting) is exempt from being, at least to a degree, believable. This thread is nitpicking though. |
