The New spiral button regenerates the galaxy with a fresh arm count and scatter, so no two spirals look alike.
Color follows structure - a warm dense core fading to blue-white arms with scattered hot stars - all procedural, no images.
The facts panel carries the real Milky Way figures - more than 100 billion stars, about 100,000 light-years across, the sun about 26,000 light-years out with a roughly 230-million-year orbit.
Galaxy 3D Simulator
Up to 100,000 points form the spiral arms on desktop (30,000 on phones so rotation stays smooth) - a real feel for how thin and vast a galaxy's disk is.

Frequently Asked Questions
What does the Galaxy 3D Simulator show?
Up to 100,000 points form the spiral arms on desktop (30,000 on phones so rotation stays smooth) - a real feel for how thin and vast a galaxy's disk is.
Is the spiral shape physically accurate?
The page is honest - the spiral is parametric art tuned to look right, not a gravitational model; the table figures are the real ones.
What are the real Milky Way numbers?
The facts panel carries the real Milky Way figures - more than 100 billion stars, about 100,000 light-years across, the sun about 26,000 light-years out with a roughly 230-million-year orbit.
