Planetary scale drawings for Whirligig World, my Kerbal Space Program mod project. Each of these drawings are out of date in one way or another, but I like them very much nonetheless. All of these drawings are done on the blue card cover of a Strathmore Vision Mixed Media Sketchbook, using Derwent Coloursoft colored pencils and black sharpies.
1) The Mesbin System. The ellipse-shaped object (which is not an egg, it’s more like a hamburger--oblate, not prolate) is Mesbin, and due to an unfortunate accident involving a piloting error of a gigantic interstellar starship, it is the homeworld. It has 60 Earth masses, and at the poles the gravity is 13 gees. Luckily, due to its 28 minute long rotation period, its equatorial gravity is only 1.3 gee. Also depicted are its moons. The blue one is the size of the Earth.
2) The Kaywell Solar System. All planets, including those which orbit Gememma, are depicted, along with some moons. The blue/white and yellow/red giants are about the size of Jupiter, and again the blue world in front of elliptical Mesbin is the size of Earth.
3) The Gememma System. Gememma is a red dwarf orbiting Kaywell, and it has planets of its own. Mandrake and Rutherford (the binary gas giant in picture 2) couldn’t be fit in, so only the limb of Rutherford is depicted. All of the bodies, including the minor and dwarf planets, and the moons, are depicted.

Whirligig World’s Mesbin is based loosely upon Mesklin, the rapidly rotating super-jovian mass icy world that is the setting for Hal Clement’s Mission of Gravity. Whirligig World is a reference to the essay he wrote in which he detailed the worldbuilding that has gone into making Mesklin.
