Orbiting Planet System

Four glowing planets orbit a radiant sun on tilted elliptical rings with depth-sorted rendering; the system drifts subtly toward the pointer.

When to use it

Dark-mode hero sections, space/sci-fi themed backgrounds, ambient screensaver panels needing gentle planetary motion.

When not to

Light-background layouts (background hardcoded dark navy). Contexts requiring legible text overlays — glow effects compete with copy.

Working with an AI agent

Every component ships agent-ready metadata. An example instruction for this one:

Add a fifth planet at r:230, s:0.18, sz:5, c:'#80ffb0' and slow the base speed from t+=0.012 to t+=0.007.

Safe to edit

  • planet orbital radii (r values)
  • orbit speeds (s values per planet)
  • planet colors (c values)
  • sun size (26*scale / 8*scale)
  • pointer drift amount (ox/oy = mx*14 / my*14)

Keep intact

  • depth-sort by z (sin(a))
  • DPR-aware canvas sizing
  • visibilitychange pause/start
  • IIFE wrapper

Known limitations

  • Background color hardcoded in CSS — must edit to change from dark navy
  • Reduced-motion draws a single static frame then stops — planets appear frozen rather than removed

More Cosmic & Space components

  • Black-hole Accretion Swirl110 heat-colored particles spiral inward across a tilted accretion disk toward a glowing event horizon; pointer movement boosts swirl speed.
  • Twinkling Starfield115 multicolor stars twinkle via sine waves; sparkle crosses appear on larger stars; stars brighten near cursor. Static fallback for reduced-motion.
  • Spiral Galaxy Rotate115 stars form a two-armed spiral galaxy rotating around a violet radial-gradient core; pointer move briefly doubles spin speed.
  • Comet Streak LoopCyan and violet comets with glowing heads and gradient tails streak diagonally across a twinkling dark starfield; click spawns an extra comet (up to 5).
  • Ringed Planet RotateAmber gas giant with tilted Saturn-like rings slowly rotates over a twinkling starfield; pointermove adjusts ring tilt and light angle dynamically.
  • Constellation Connect46 drifting star nodes auto-connect with faint magenta lines when close; cursor draws lines to nearby stars and brightens them on hover.
