Titan diameter and size comparison
Titan’s mean body diameter is 5,149.52 kilometers. The orange haze identifies the moon, but extended atmospheric layers are excluded from the measured disk.

A little more perspective
The radius in JPL’s satellite table is 2,574.76 kilometers. A photograph that includes a detached haze layer can have a different apparent boundary; this idealized globe fixes the boundary to the stated body-size reference.
The displayed diameter is 2 × 2,574.76 km = 5,149.52 km. Doubling the source radius uncertainty gives ±0.04 km for diameter. The source defines mean radius through an equivalent-volume sphere. Its review date is not a new measurement date.
Quick facts
Titan’s mean body diameter is 5,149.52 kilometers. The orange haze identifies the moon, but extended atmospheric layers are excluded from the measured disk.
For a presentation or a research note, include the subject, the measurement definition, and the measurement used. A picture alone cannot explain those choices. The comparison guide explains how to export an image and its source notes together.
