Larissa — moon orbiting Neptune, shown live in Cosmoscope, a real-time 3D map of the universe.
A dark, cratered relic of Neptune’s original moons, shattered and reassembled after Triton’s violent arrival.
Cosmoscope puts Larissa 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 Larissa 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 Larissa where it was on any past date, or where it will be years from now.
