This list covers 6 moons whose names start with the letter K, ranging from “Kalyke” to “Kerberos.” Most of them are small, irregular bodies orbiting the giant planets of the outer solar system. They travel in distant orbits, often in retrograde paths, which makes them some of the most fascinating and hard-to-spot objects in our solar system.

Moons are natural satellites held in orbit around a planet or dwarf planet by gravity. They range enormously in size, from massive icy worlds to tiny rocky fragments just a few kilometers wide. Many moons get their names from mythology — and the K moons are no exception, drawing on Greek, Norse, Inuit, and Roman legend.

Below you’ll find the table with each moon’s name, parent planet, diameter, discovery year, and description.

Moon: The name of the moon, which typically comes from a mythological figure tied to the culture associated with its parent planet.

Parent Planet: The planet or dwarf planet the moon orbits — useful for understanding where in the solar system it lives.

Diameter (km): The moon’s approximate width in kilometers, giving you a quick sense of how large or small it is compared to others on the list.

Discovery Year: The year astronomers first confirmed the moon’s existence, often using advanced telescopes or space-based observations.

Description: A short overview of each moon’s key traits, including its orbit type, group classification, and the story behind its name.
