Question	—	How to calculate the light received by a planet during a binary star eclipse? I'm building up a spreadsheet on worldbuilding (Stars, Planets, Moons etc.) and i'm struggling to find an equation, or a group of equations to help me figure out the light received by a planet orbiting a P-Type Binary during both of its stellar eclipses. I already have the light coming from the sta... (more)	—	over 7 years ago
Question	—	Calculating the orbits of binary stars around their barycentre I've been building a world, partly for test reasons (making sure my spreadsheet works, and so i know what i need to add to it) and partly for fun, but for calender reasons i need to know the orbital period of my binary star system. More specifically, as i am putting this in a spreadsheet, i need the... (more)	—	over 7 years ago
Question	—	How to construct atmospheric pressure belts for my world? I read somewhere that the size of a planet can influence the number of pressure belts (the areas of high and low pressure that cycle wind, heat and moisture about the globe) How would you go about constructing these belts when worldbuilding and how are they affected by the planet's size? Are they al... (more)	—	over 7 years ago
Question	—	How would a four or five winged creature, such as a microraptor, fly? Microraptors are cretaceous-period dinosaurs with feathered wings on both their forelimbs and back-limbs. Despite this, they are not considered 'true flyers' as it is believed they used their five 'wings'(The tail counts as one due to its purpose in generating 'lift') to glide from tree to tree and ...
