Orbitviewer is a 3D web app by Vera C. Rubin Observatory that visualizes the motion of Solar System objects using real data processed by the Minor Planet Center.
Planets, dwarf planets, near-Earth objects, main belt asteroids, trans-Neptunian objects, comets, and even interstellar visitors — all displayed in three-dimensional space. You can rotate the view, zoom into individual objects, filter by type, or search for a specific object by name or designation. Click on anything for detailed orbital information.
A time slider lets you move between 1900 and 2100 and watch the Solar System's structure change over time. Four performance modes are available: from 16,000 objects for smartphones to one million for powerful desktops.
The standout feature is the discovery counter, which updates in real time as Rubin finds new objects. And it finds a lot: in just ~10 hours of observations, the observatory detected 2,104 previously unknown asteroids. In its first year, Rubin is expected to discover more Solar System objects than all observatories combined have found in the past 150 years.
