Earth

Earth — planet, explore its interactive 3D model in Cosmoscope.

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

Home. Here, we learned to make fire, tell stories and give the stars names. Along its rivers we built cities; across its seas we carried our languages, music and dreams. Whether our future unfolds beneath these clouds, across the Solar System or around distant stars, Earth will always be where our story began.

Explore Earth in 3D

Cosmoscope places Earth 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.
