Overview
Introduction
This generator draws a small, self-contained piece of space art: a shaded sphere standing in for a fictional planet, with optional rings and a scattering of craters and cloud bands.
Every part, the base color, whether it has rings, and where its surface features land, comes from fresh randomness each time you generate.
What Is Random Planet Generator?
A procedural SVG generator that builds a gradient-shaded circle (the planet body), optionally paired with a ring system, plus a handful of crater and cloud-band details clipped to the body's outline.
It leans on a small set of reusable SVG techniques, radial gradients for shading, split half-ellipse arcs for rings, and clip-path for containment, rather than any external rendering library.
How Random Planet Generator Works
A radial gradient centered toward the upper-left of the circle blends from a lighter to a darker shade of one random hue, giving the flat circle a subtle 3D-sphere look.
If a ring is included, it's drawn as two separate half-ellipse path arcs sharing the same rotation transform: one rendered before the planet's circle (so it appears to pass behind it) and one after (so it appears to pass in front).
Three to six random craters and two to four translucent cloud-band ellipses are placed within the planet's radius, then wrapped in a <g> element clipped to the exact same circle so nothing spills past the edge.
When To Use Random Planet Generator
Use it for quick decorative space-themed art, a placeholder planet icon, or a fun bit of generative art to download as a scalable SVG.
It's well suited anywhere a stylized, simplified planet graphic fits better than a photorealistic space render.
Often used alongside Random World Map Generator and Random Landscape Generator.
Features
Advantages
- Produces a crisp, infinitely scalable SVG rather than a fixed-resolution raster image.
- The ring can be forced on, forced off, or left to a random 50/50 chance.
- Every regeneration produces a genuinely different color, crater layout, and cloud pattern.
Limitations
- The ring system's front/behind effect is a simplified two-arc illusion, not a true 3D-projected ring.
- Craters and cloud bands are simple flat ellipses; there's no lighting interaction between them and the sphere's gradient shading.
- This is stylized generative art, not a scientifically accurate planetary rendering of any real or hypothetical world.
Examples
Best Practices & Notes
Best Practices
- Regenerate a few times to compare ringed and ringless results before picking a favorite.
- Download the SVG if you want to recolor or edit individual craters afterward in a vector editor.
Developer Notes
The clip-path applied to the craters/cloud-bands group reuses the exact same circle geometry (center and radius) as the planet's own body circle, which is what guarantees surface details never visually overflow past the sphere's edge regardless of how randomly they're placed.
Random Planet Generator Use Cases
- Decorative space-themed art for a game, app, or presentation
- A quick placeholder 'planet' icon or avatar
- Illustrating SVG gradient, clip-path, and layered-arc techniques
Common Mistakes
- Expecting the ring's front/behind effect to hold up under closer inspection — it's a simplified two-arc illusion, not real 3D geometry.
- Treating the output as any kind of scientifically accurate planet rendering.
Tips
- Toggle the ring off for a cleaner, more minimal planet.
- Try several regenerations side by side to see the range of hues and surface-feature layouts.
