Space Time
The outer shepherd moon of Uranus's epsilon ring, paired dynamically with Cordelia.
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.
Ophelia is placed by solving a Keplerian orbit around uranus at the simulation time (a = 53,765 km, e = 0.011, i = 0.2°, period 0.4 d).
Ophelia: mean radius 16 km. These values are bundled with the object record and drive the rendered size.
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.
Nothing on this page is a reconstruction or a schematic; every record above is observed, catalogued or computed.
