Solar Wanderer — A 1:1 Real-Time Solar System in Your Browser
A free, open-source solar system explorer powered by real NASA JPL ephemerides. Every planet and moon is at its true position right now (accuracy ≤0.074°), at true 1:1 km scale — from the Sun's surface to the Oort Cloud at 100,000 AU. Land seamlessly on planets, walk on the Moon and Mars, dive into Earth's oceans, fly freely at up to 2 AU/s, and accelerate or reverse time. Physically-based atmospheric scattering reproduces the Mars blue sunset and the Venus orange sky. No install, no account, no ads.
