Astronomers have been discovering new moons almost every years for the past few decades (see plot below). All of these moons have orbital … It is also the planet around which the largest number of moons revolve around the solar system. There are 79 known moons of Jupiter. Only recently, (in 2018) 12 new moons were discovered by a team of astronomers at the Carnegie Institution of Science headed by Scott Shepard, taking the total to where it is today (79).

Jupiter’s regular moons consist of the Galilean moons and an inner group of 4 small moons with diameters less than 200 km / 124 mi, and orbits with radii less than 200,000 km / 124,274 mi. Combined, scientists now think Jupiter has 79 moons. The new discovery brings Jupiter’s total number of moons to 79, the highest of any planet in solar system, the institute said in a statement. Others are awaiting official names. This includes Europa, which is covered in an icy crust that sits above an ocean of salty water. Jupiter has the most moons of any planet and astronomers continue to discover more over time. The latest survey of the region around the gas giant turned up a dozen new moons, including an oddball that was going in the wrong direction. The most massive of the moons are the four Galilean moons, which were independently discovered in 1610 by Galileo Galilei and Simon Marius.They were the first objects … Jupiter has 79 known moons, the largest number of moons for a planet in the solar system, that vary in size and characteristics. The many moons of Jupiter have long fascinated those interested in outer space. There are many interesting moons orbiting the planet, but the ones of most scientific interest are the first four moons discovered beyond Earth—the Galilean satellites. The regular satellites have almost circular orbits and are prograde while … Jupiter most likely has many more moons the the 79 we know of so far. Jupiter has the second largest number of moons with reasonably stable orbits of any planet in the Solar System.. Twelve new moons orbiting Jupiter have been found—11 "normal" outer moons, and one that they're calling an "oddball." At a time when Earth has one moon, Jupiter has 79 moons. Other Moons of Jupiter.
