For another setting, I was sketching out a star system with 0.5 solar mass primary and a planet orbiting it with a 30,000,000-kilometer semi-major axis.
It's easy enough to find the year length (46 Earth days), but I had a few questions:
1. Given an eccentricity of 0.5, how many days does the planet spend in each quarter of its orbit (quarter: as measured by distance along the circumference)? Basically, how long is each season? Also, what is the periapsis in kilometers?
2. Given an eccentricity of 0.7, how many days does the planet spend in each quarter of its orbit? Also, what is the periapsis in kilometers?
Assuming for sake of argument that the planet was habitable and Earth-like, and that it maintained a fairly short rotation (under 48 hours), what would that high eccentricity and short year do to weather?
The short heat pulse and long cooling are predictable, but they're happening over (basically) a long month. What sort of winds and weather patterns would develop? General chaos, or something regular and predictable?
