How to use the Pixel Planet Generator
- Pick a type: Terran, Gas giant, Lava, Ice, Moon / rocky, Desert, Star or Asteroid.
- Set the size, the frames per turn and where the light comes from; turn the ring, clouds, dither and outline on or off.
- Change the colours if you like, and press New planet until you get one you like.
- Download the GIF (or GIF 4×), the sprite sheet, or just this frame.
Using it in your game
The sheet has 10 frames per row and is one full turn, so loop it. For a slow, calm spin use more frames (60-120) at 8-12 fps; for a small background planet, 16-32 frames is plenty. Rings and the star's corona take room, so the planet is drawn smaller inside the same square; keep every planet sprite centred.
Frequently asked questions
What can it make?
Terran planets (oceans, land, clouds, polar caps), gas giants (bands, a storm and an optional ring), lava worlds with glowing cracks, ice worlds, cratered moons, desert planets, stars with a flickering corona, and lumpy asteroids that tumble.
Does the rotation loop?
Yes. The surface is 3D noise turned around the planet's axis by exactly one full turn over the frames you pick, so the last frame flows straight into the first. Play the sheet on repeat.
Is it real pixel art?
Every pixel is hard-edged and each planet uses a small fixed palette (about 5 to 12 colours), shaded from highlight to shadow, with optional dithering on the shadow edge and a dark outline. Change the main colours to match your game.
How do I use it in my engine?
Download the sprite sheet (10 frames per row) and play it as a looping animation, or use the GIF. Each seed gives a different planet; the same seed and settings always give the same frames.
Is anything uploaded?
No. Everything runs in your browser, with no account and no limit. The free pixel_planet tool on the Voidless MCP server makes the same planets from Claude Code or Cursor.
