Default Planet Generation

I generated a planet and system using Space for a fantasy game idea that I have and I wanted to share the results with you all since the ending result was very interesting. Also, for the scientists out there, I wanted some input on how the world would be acting from a meteorological and geological standpoint.

Note: I have not generated the other planets yet, and was not going to do that today.

Calculate the temperature at apastron (maximum separation) and periastron (minimum separation). You will find the result interesting.

That's not so easy. The thing you have to remember about elliptical orbits is that the part of the orbit which is near the Sun is a shorter period than the part of it which farther out than the median distance. Therefore winter (which thanks to a lack of axial tilt is produced by being actually remote from the sun) is, generally speaking, longer than summer. Northerly climes will be _very_ uninhabitable in the depth of winter, which lasts a long time due to the 2x year length. I wouldn't surprised to see hibernation as a common trait in northern animals.

Umm, how do I do that? I didn't see that in Space

Ok I go the temperatures, and wow, maybe I should tone down the eccentricity

A planet functions as a substantial heat sink, so living on an eccentrically orbiting planet won't be quite as extreme as summering on Venus and spending the winter on Mars.

Stay away from deserts on the interior of a continent, though.

True, but who wants runaway greenhouses in summer, and runaway glaciation in winter? Exactly how much a life bearing planet can "hold" it somewhere in the middle is anyone's guess.

Maybe it could have a vast underground eco system.

That's what I did way back in my D&D days with my eccentric planet evolved race. Some animals hibernated in deep underground caverns and created a whole separate type of life. Maybe I just wanted my albino apes to show how my flyndarans saw humanity on our eternal spring planet. :)
