Overview

A dynamic physics playground.

Solar System renders the Sun and the eight planets on Keplerian orbits around it, with sizes and distances scaled for visibility. Time can be accelerated by orders of magnitude so you can watch a year pass in a second.

Drag to rotate the camera, scroll to zoom, click a planet to follow it. Adjust the time scale, planet sizes, and trail length in the sidebar.

Features

Built for physics-scale experimentation.

01 / Spotlight

Real-time render of

The Sun and eight planets on Keplerian orbits.

How to use

Workflow

Steps take about a minute.

Drag the background to rotate the camera and scroll to zoom. Click a planet to follow it. Use the sidebar to set the time scale, planet sizes, and trail length. Export PNG/JPG from the toolbar.

FAQ

Common questions

Are the orbits to scale?+

Orbital distances and planet sizes are compressed so everything fits on screen at once. Use the time scale slider to see real-time motion or accelerate to thousands of years per second.

Can I add my own planet?+

Not in the current build. The sidebar exposes the eight planets and lets you tune their trails and sizes, but custom bodies aren't yet supported.
