Which four specific moons constitute the Galilean moons observable near Jupiter?
Answer
Io, Europa, Ganymede, and Callisto
When observing Jupiter, which is the largest planet in our Solar System, one of the most rewarding sights is the visibility of its four largest satellites, known collectively as the Galilean moons. These four bodies—Io, Europa, Ganymede, and Callisto—were first observed telescopically by Galileo Galilei. Under telescopic magnification, these moons frequently present themselves as distinct, small, bright points of light positioned in a line adjacent to the massive Jovian disk. Observing these distinct points, sometimes appearing to transit across Jupiter's face, confirms the presence of a complex satellite system surrounding the giant planet.
