Space Time
Mars's larger and innermost moon. One of the smallest moons in the solar system.
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.
Phobos is placed by solving a Keplerian orbit around mars at the simulation time (a = 9,376 km, e = 0.0151, i = 1.1°, period 0.3 d).
Phobos: mean radius 11.3 km. These values are bundled with the object record and drive the rendered size.
Real spacecraft imagery on an approximate ellipsoid. Resolution and baked-in lighting vary; this is not a detailed shape model.
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.
