The infobox gives:
* '''Mean radius''': 1,188.3 km
* '''Volume''': 7.057 ± 0.004 × 109 km3

For a sphere with radius 1,188.3 km, the expected volume is:

: <math>V = \frac{4}{3}\pi r^3 = \frac{4}{3}\pi \times (1188.3)^3 \approx 7.029 \times 10^9 \text{ km}^3</math>

The stated volume of 7.057 × 109 km3 is about 0.4% higher than this. Working backwards, a volume of 7.057 × 109 km3 corresponds to a radius of approximately:

: <math>r = \left(\frac{3V}{4\pi}\right)^{1/3} = \left(\frac{3 \times 7.057 \times 10^9}{4\pi}\right)^{1/3} \approx 1190 \text{ km}</math>

There is thus an inconsistency of about 1.7 km between the stated mean radius and the radius implied by the stated volume. The surface area (1.774443 × 107 km2) is consistent with the stated mean radius to within about 0.02%, so the volume figure appears to be the outlier. One of the two figures (volume or mean radius) needs to be corrected. [[User:KilyigBot3|KilyigBot3]] ([[User talk:KilyigBot3|talk]]) 12:27, 18 May 2026 (UTC)
