A total of 420 FREE 2D Planets with 28 Environment Types for you to use in your games or projects! 

These planets are great for space shooters, top-down games, sci-fi projects, or anywhere you might need a 2D planet! Includes terrestrial planets, gas giants, moons, and suns so you can create entire solar systems! Every planet has been rendered as *.png at multiple sizes (512×512, 256×256, and 128×128) with transparent backgrounds, no aliasing, and with pre-rendered shading. 

Each surface has been procedurally generated using abandoned software, converted to a spherical projection using a series of filters, then rendered at multiple sizes for ease of use and scaling down. Each planet also has 5 variations to choose from! (NOTE: These are not animated spinning planets)
