About Space Time

An interactive 3D visualization of our solar system and beyond

Overview

Space Time is a scientifically accurate solar system simulator that lets you explore the cosmos from your browser. Built with Three.js and real astronomical data from NASA JPL Horizons, it provides an immersive experience of our cosmic neighborhood.

Key Features

  • Accurate Orbital Mechanics - Planet positions calculated using NASA JPL ephemeris data and the astronomy-engine library
  • Interstellar Visitors - Track 3I/ATLAS, 1I/Oumuamua, and 2I/Borisov as they pass through our solar system
  • Time Control - Travel through time from 2015 to 2036, adjustable from real-time to 1 year per second
  • Reference Frames - View the solar system from different perspectives: heliocentric, geocentric, or centered on any object
  • True Scale Mode - Toggle between artistic visualization and scientifically accurate object sizes
  • Apollo Missions - Replay historic Apollo 11, 13, and 17 missions with accurate trajectories
  • Guided Tours - Pre-configured views of eclipses, planetary conjunctions, and interstellar encounters
  • Nearby Stars - Explore our stellar neighborhood up to 40 light-years away, including Proxima Centauri and Zeta Reticuli
  • VR Support - Full WebXR compatibility for immersive virtual reality exploration
  • Real Planet Textures - High-resolution surface maps for all planets and moons

Objects Included

  • The Sun and all 8 planets with accurate orbital and rotational dynamics
  • Earth's Moon and Jupiter's Galilean moons (Io, Europa, Ganymede, Callisto)
  • 5 dwarf planets: Pluto, Ceres, Eris, Makemake, Haumea
  • Asteroid belt and Jupiter Trojan asteroids
  • Kuiper Belt and Oort Cloud visualization
  • Voyager 1 and 2 spacecraft trajectories
  • James Webb Space Telescope at L2
  • Earth-Sun and Jupiter Lagrange points
  • 10 nearby star systems
  • 3 known stellar black holes (Gaia BH1, BH2, BH3)
  • 13 major constellations with star patterns

Data Sources

  • NASA JPL Horizons System for ephemeris data
  • Minor Planet Center for interstellar object orbital elements
  • ESO/S. Brunier for Milky Way panorama skybox
  • NASA Visible Earth for planet textures

Built with Three.js, TypeScript, and Vite
