Photograph of Titan, a moon of Saturn.

OVERVIEW

] MOON

Titan is a moon of Saturn. It orbits Saturn at a mean distance of 1 221 900 . It has a mass of 0.02 and a mean radius of 0.40 · 2575 . It was discovered in 1655.

The only moon with a substantial atmosphere, and the only world besides Earth with liquid on its surface — lakes and rivers of methane under an orange haze.

THE MODEL

] CATALOGUED RADIUS
DRAG TO ORBIT

CALCULATED · NOT AN OBSERVATION · CATALOGUED RADIUS · DENSITY 1.88 G/CM³ · RADIUS 2570 KM · LIT FROM WHERE THE SUN IS · SURFACE FROM A GLOBAL MAP · AT ITS REAL LONGITUDES

Drawn from the catalogued radius and from the same properties the picture at the top of this page uses, at the distance a flight to it would stop. The surface is a global map rather than a pattern — a mosaic of real images, wrapped on by latitude and longitude. It is mapped at 938 nanometres, the one wavelength that reaches the ground through the haze; in visible light Titan is a featureless orange ball. Longitude zero on it is laid where longitude zero on the body actually is at the moment this page was built, so a feature is drawn where the feature is. The map comes from NASA, in the public domain. Drag it, or use the arrow keys, to look from another direction. The stars behind are the 498,631 this catalogue holds real distances for, at their real positions and drawn from where the camera actually is — so the constellations are wrong, and that is the point. This is the sky from there, not the sky from here.

OBSERVING

CATALOG DATA

] 25 FIELDS

The raw catalogue values, as the source published them, with the error bars where one was published — sorted by what each set of figures is about rather than by the order they happened to be stored in.

WHAT KIND OF THING IT IS

THE ORBIT

The shape of the path, where the object sits on it, and the instant those figures were true of. An orbit is a fit to observations and drifts away from the real one either side of its epoch.
