· super Earth (the super giant part can be nixed if impossible)
· rings system made of silicate, size is still to be determined (but the wider, the better)
· non tilted axis
· there are moons inside the rings but they're small (nothing like Earth's moon)
· high eccentric orbit
The main question
1)The planet is supposed to be habitable (up to debate), since the planet has no tilted axis, I suppose the rings would cast their shadow along the equator all year around. So what would be exactly the weather in the area in the shadow if it's wide enough? There would be no sunlight ever, so I suppose it would be a very cold weather. Can life still grow there? Or would it be a total icey no man's land? Would there be some sort of micro climate all along the equator?
(the habitability of the area/biome under the shadow is also something I'm wondering. The planet is supposed to habitable, which I'm not sure myself. Given the gravity and the lack of bigger moon (therefore potentially having an unstable tilt axis and no tides).
If such a planet is habitable, what kind of weather and therefore biome, would the ring's shadow bring on the equator?
(I also want to apologize if my post was unclear as I'm not a native English speaker! I'm still learning the rules.)
