Steer a planet with arrows A vector is an ordered list of numbers. On this planet, three numbers can place a pin, fly a plane through the wind or aim the sunlight. Five short steps, about ten minutes.
Start step 1 Just explore
Tap the planet or press Enter to start
Step Pause motion Reset view

The vectors lesson covers the same ideas without 3D.
Reload the page What does it mean for two items to be close? To answer that, we first need numbers to compare. This planet runs on them: every pin, plane and patch of sunlight is placed by a short list of numbers called a vector.
A teaching simulation. Every number on this page is computed by the scene's own code; no AI model runs here. Distances are in planet units (radius 10). Built by Jonathan Simone with AI coding assistance. The starting prompt comes from OhMyUnicorn's one-prompt planet experiment . 3D by Three.js 0.128.0, used under the MIT licence (notice ).
