A changing census
The number of confirmed satellites grows when new observations allow a body to be recognised and its orbit determined. According to NASA, Saturn had 293 confirmed moons in August 2026. The count refers to that date and may be updated.
A varied family
Titan is larger than Mercury and has a dense atmosphere. Enceladus is a small icy moon with a global ocean below its surface. Many other moons are much smaller and follow distant orbits.
Jupiter and its moons
Jupiter has numerous satellites as well. The four large Galilean moons — Io, Europa, Ganymede and Callisto — are very different worlds. A comparison of counts requires data from the same date and the same definition of confirmation.
