What are Jupiter's four large named moons called?

Jupiter's four large named moons are known as the Galilean Moons, a title that honors the astronomer Galileo Galilei, who discovered them in 1610. These moons—Io, Europa, Ganymede, and Callisto—are significant not only because of their size and unique characteristics but also due to their historical importance in the study of astronomy. The Galilean Moons are the largest of Jupiter's moons, and they display a variety of geological features and atmospheres that are of great interest to scientists.

The term "Galilean Moons" specifically highlights their discovery by Galileo, distinguishing them from other moons that Jupiter hosts. This naming underscores the contributions of early astronomers to our understanding of celestial bodies and the dynamics of our solar system. In contrast, the other names presented, such as the Titan Moons and Orion Moons, either refer to other celestial bodies or have no relevance to Jupiter's major moons. The Jovian Moons could be a general or informal term used to refer to any of Jupiter's moons but does not specifically identify the four large ones recognized historically and scientifically.
