my planet, aptly named Prima Nicholi, part of the nearby system Alpha Nicholi, will be a nice planet, with a core made of solid Platinum. too bad if you want to get to it, as it's sealed underneath a big molten mantle and its crust is tectonically active, and there is a lot of really bad weather like really, the bahamas havent seen nothin yet
as for how big the planet is, not sure... probably like saturn size. it will have a lot of pretty rings that will disappear in a few million years. orbit is quite close to circular, but of course nothing is perfect especially on an interplanetary scale. its most remarkable feature will be its outer appearance, which will be very blue for about half of its orbit and very orange for the other half. think cotton candy for its texture.
