Neptune — planet, shown live in Cosmoscope, a real-time 3D map of the universe.
The first planet found by mathematics before telescopes — its gravity’s tug on Uranus gave it away. The windiest world known: supersonic jets tear through its blue methane haze at 2,100 km/h.
Cosmoscope puts Neptune at its true position in the solar system, computed from JPL-derived ephemeris and updated continuously. Open the live 3D view to see, in real time, how far Neptune is from the Sun and from Earth right now, how many minutes or hours light takes to cross that gap, and how fast it is moving along its orbit. Scrub the timeline to place Neptune where it was on any past date, or where it will be years from now.
