SpaceTrekk – Real-time 3D Solar System Simulator with Accurate Physics

Summary: SpaceTrekk is a scientifically accurate, interactive 3D solar system simulator that uses NASA JPL data and Keplerian mechanics to render planetary orbits with sub-kilometer precision. It allows users to explore planets, moons, constellations, and spacecraft in a WebGL environment and travel through time from 1900 to 2100 to visualize celestial motions.

What it does

SpaceTrekk calculates planetary positions using Keplerian orbital elements and Newton–Raphson solvers to produce elliptical orbits accurate to within one kilometer. It renders an explorable 3D solar system with detailed models of planets, dwarf planets, moons, spacecraft, and constellations using Three.js and WebGL.

Who it's for

It is designed for students, educators, space enthusiasts, and curious users who want to visualize orbital mechanics, track real spacecraft, and explore the solar system’s celestial dynamics over time.

Why it matters

SpaceTrekk provides precise, data-driven visualization of planetary motion and spacecraft trajectories, enabling users to understand and observe the physics governing the solar system across past, present, and future dates.
