You'd have to define what counts as a circular orbit for that though, given that it's always an ellipse.

Survive', maybe. 'Thrive', probably not.


Yes, but my point was that even if a given planet has extreme surface temperatures that doesn't mean it doesn't have also some potential biome with more temperate temperatures, somewhere. I used Venus as an example because it's the closest thing to hell we know positively about. wink





They let me use this!

any orbit with an eccentricity <0.01 is circular enough dry

In which case, Venus and Neptune would be the only planets of our Solar System with orbits circular enough to qualify. I don't really see the point of restricting planets with much closer perihelions, but if it's considered a problem, counting the temperature at apohelion is a much easier fix than an arbitrary eccentricity limit.

There are several possible ways to go about this, perhaps none are ideal. An issue that occurs to me with going by perihelion or aphelion temperature is that there is further variation in multiple-star systems due to the stellar orbits. Usually this is small, but not always, and for challenge purposes fractions of Kelvin may matter.

Choosing to only accept planets with eccentricities below some arbitrarily chosen threshold doesn't seem like the best route either, and even a perfectly circular orbit will not avoid the multiple-star problem. So we could dismiss planets in multiple star systems (I'm not a fan of this idea). Or we could go by time-averaged temperature (lolno). I would propose going by the highest temperature that the user finds for their planet as a fairly straightforward option, and it also does not reject any planets already entered. And if a user doesn't want to check the temperature over time, no problem -- it's still a valid entry but might not be the best possible one.

That is my view on the matter anyway; ultimately I think the OP should decide and ensure participants are on the same page.

Donatelo200, that planet looks really cool!
And i'm sure its a temperature record breaker.(With life)

Donatelo200's planet is an interesting one indeed, and he didn't even include a angle to really tell the whole story...

The planet at the time of it's highest temp, is sandwiched inbetween a Yellow Dwarf and an Orange Dwarf.

This means, that it's temperature goes from 390K to 479K in about 10 years. That's a 89° Celsius or 160° Fahrenheit difference.

Here's an image of the planet where both halves of it are illuminated:


And here is where it is in it's orbit:

Hmm... That excludes a relatively famous Terra with life...

I'm not gonna tell you which one, but the eccentricity is 0.01671123.

In fact, there is only one planet in that entire system with such low eccentricity, and its habitability is about the same as that of an overclocked pressure-cooker full of Drain-O.
