Salacia — dwarf planet, shown live in Cosmoscope, a real-time 3D map of the universe.
A dim, dark world named for the Roman goddess of the sea. Its low reflectivity and density make it a borderline dwarf planet — round, but never officially crowned. Its moon Actaea helped weigh it.
Cosmoscope puts Salacia 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 Salacia 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 Salacia where it was on any past date, or where it will be years from now.
