Titan

Saturn's largest moon. Only moon with a dense atmosphere and liquid lakes on its surface.

Kepler elements Orbit basis, the same label the app shows on the selection card.

Every aspect, with its origin

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.

Orbit Computed

Orbit from mean elements

Titan is placed by solving a Keplerian orbit around saturn at the simulation time (a = 1,221,870 km, e = 0.0288, i = 0.3°, period 15.9 d).

MethodTwo-body propagation of the stored elements by the shared orbit service; no perturbations.
LimitA two-body orbit ignores perturbations; positions drift from the true ephemeris away from the element epoch.

Bulk properties

Titan: mean radius 2,574.7 km. These values are bundled with the object record and drive the rendered size.

Appearance Reconstructed

Visible haze or infrared surface

Orange haze approximates the visible atmosphere. Choose Infrared surface for the Cassini ISS 938 nm mosaic (2004–2014); it is not visible-light color.

MethodThis describes the displayed appearance only; it does not certify catalog dimensions, orbital elements or unobserved geology.

Titan: the map behind the view

Cassini ISS 938 nm, 2004–2014. Brightness-normalized near-infrared mosaic, not visible-light color or elevation. The publisher’s uniform gray coverage gap is marked gray-blue; visible haze obscures the surface.

MethodSource maps are compared with a physical globe or rings under simulated illumination. The image and camera view are not registered.
LimitCassini ISS 938 nm, 2004–2014. Brightness-normalized near-infrared mosaic, not visible-light color or elevation. The publisher’s uniform gray coverage gap is marked gray-blue; visible haze obscures the surface.
