Space Time
Neptune's largest moon. The only large moon with a retrograde orbit, suggesting it was captured.
One record per aspect. The origin says what kind of thing each value is; the source says where it came from; the limit says what it cannot tell you.
Triton is placed by solving a Keplerian orbit around neptune at the simulation time (a = 354,759 km, e = 0.000016, i = 156.9°, period 5.9 d).
Triton is presented using voyager-mapped surface; terrain-free observed-color continuation in the unmapped cap; measured bulk atmosphere data.
Triton: mean radius 1,353.4 km. These values are bundled with the object record and drive the rendered size.
Gray-blue marks the unobserved northern terrain. No colors or terrain are continued into the missing coverage.
Voyager 2, 1989 enhanced color. Unmapped northern terrain remains gray-blue, with no invented terrain. The source publisher interpolated over old map grid lines; photographic lighting is retained.
The short description and the fact list are written by the Space Time authors for orientation. They are not quoted from a catalog field and carry no citation of their own.
