Sun

Sun — star, explore its interactive 3D model in Cosmoscope.

Explore Sun in a live 3D Solar System. Follow its calculated motion and inspect real astronomical data, distances and orbital facts.

A middle-aged yellow dwarf holding 99.86% of the solar system’s mass. Light leaving its surface now took roughly 100,000 years to escape the core — then just over 8 minutes to reach you.

Explore Sun in 3D

Cosmoscope places Sun in the Solar System using astronomical ephemeris or orbital elements, updated for the simulation time. Explore its calculated motion, distance and orbital facts in the interactive 3D view. Accuracy depends on the orbital model and its valid time range.
