Ahoy - so this is a rather multi-faceted question, but I need it properly answered for a creative project of mine. I could think of no better place to ask it, so forgive me if it's misplaced. I have on paper before me a fictional planet that does not rotate. It's general shape is a truncated icosahedron (that of a classic soccer ball), with 32 isolated faces (12 pentagonal, 20 hexagonal, all separated by artificial mountains + potentially an invisible atmospheric barrier). It is orbited by an artificial sun that provides energy equivalent to that of our own, though has negateable mass, an orbital distance comparable to high-orbiting satellite, and an orbital period of 20 hours, giving us 10 hour days at the equator (the required distance to allow for this speed I have not yet bothered with). In addition to the sun is a mass-less moon (effectively a giant mirror), the orbit of which I am not certain about. Anyhow - moving on. The planet is artificial, and hence lacks the organic layers integral to the maintenance of a magnetic field. The system is entirely isolated - that is to say, assume for the question's sake that there is nothing beyond the orbit of the sun, and hence no extra-system cosmic bombardment. Here are the planet's values: M = 3.07e24 kg Radius = 5.021e6 m Surface Gravity = 8.122388658 m/s^2 The artificial sun has a perfectly circular orbit about the equator of the planet. Each of the 32 regions has an independent atmospheric composition (how, I don't know yet), and you should assume that any winds in a region's air would be specific to the region's unique atmosphere and temperature (and thus pressure). The surface is also artificial, and so does not flow. There is no tectonic activity. What sort of issues would arise with a non rotating planet that artificially maintained a stable atmosphere, that presumably lacked a magnetic field, and that was the center of it's own small solar system? Thanks, and sorry.
