Space Time — Interactive 3D Solar System Visualization

Space Time is a free, browser-based 3D visualization of our solar system. Explore the planets, moons, stars, and comets with accurate positions powered by real astronomical calculations.

Explore the Solar System in 3D

Navigate a real-time model of the solar system with all eight planets — Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune — plus dwarf planets like Pluto, Ceres, and Eris. Every object is positioned using the astronomy-engine library for scientific accuracy.

Surface Views

Stand on the surface of Earth and look up at a realistic sky. See the Sun, Moon, planets, and over 500,000 stars in their correct positions. Watch the sky change through day, twilight, and night with a physically-based sky dome.

Eclipse Visualization

View solar and lunar eclipses from space or from Earth's surface. Time-travel to past and future eclipses with precise date controls.

Star Maps and Constellations

A three-tier star catalog renders up to 500,000 stars. Toggle constellation lines and labels. Deep sky objects include nebulae, star clusters, and galaxies from the Messier catalog.

Interstellar Visitors

Track interstellar objects passing through our solar system: 1I/'Oumuamua, 2I/Borisov, and 3I/ATLAS with accurate hyperbolic orbit calculations.

Time Controls

Speed up, slow down, or reverse time. Jump to any date from thousands of years in the past to the far future. Watch orbital mechanics in motion.
