How many natural satellites does Jupiter …

There are 79 known moons of Jupiter, not counting the number of moonlets likely shed from the inner moons. The most massive of the moons are the four Galilean moons, which were independently discovered in 1610 by Galileo Galilei and Simon Marius and were the first objects found to orbit a body that was neither Earth nor the Sun. Much more recently, beginning in 1892, dozens of far smaller Jovian moons have been detected and have received the names of lovers or daughters of the Roman god Jupiter or his Greek equivalent Zeus. The Galilean moons are by far the largest and most massive objects to orbit Jupiter, with the remaining 75 known moons and the rings together composing just 0.003% of the total orbiting mass. The number of moons known for each of the four outer planets up to October 2019. Jupiter currently has 79 known satellites.
