Jupiter moons, why do you have more than one? Jupiter has a high number of natural satellites, currently estimated at 67, making it the planet with the largest procession of satellites with reasonably safe orbits of the solar system.
The major were discovered in 1610 by Galileo Galilei and were the first objects identified in orbit to an object that was not the Earth or the Sun.
The precise number of satellites will never be exactly quantified because the frozen fragments that make up its rings can technically be considered as such; Moreover, to date, the International Astronomical Union did not want to put a precise distinction arbitrary line between minor and major satellites icy fragments.
Regular satellites constitute the remains of an ancient population of mass satellites similar to the Galilean satellites that would be formed from the coalescence of dust inside a disc, similar to the protoplanetary discs around newly formed stars. The satellites of Jupiter owe their name to the characters of Greek mythology related to Zeus, father, and king of the gods according to Greek religion, which is equivalent to the Roman Jupiter, which takes its name the planet.
Although the distinction is not strictly defined, the satellites of Jupiter can be classified as follows. Inner satellites – orbit very close to Jupiter; they are part of, in order of distance from the planet: Metis, Adrastea, Amalthea, and Thebes. The main group – consists of the four major system moons: Ganymede, Callisto, Io, and Europa.
Irregular satellites are basically instead of the smaller objects, more distant and more eccentric orbits than the regular satellites. Themisto, The Himalia group, Carpo, S / 2003 J 12, The Ananke group, The Pasiphae group, S / 2003 J 2 and S / 2011 J 1. Changes in the population of Jupiter’s satellites may result from the temporary capture of several small bodies in the solar system, that the attraction of the great mass of the planet moved on Zeno centric orbits; temporary adjective can be understood either on a time scale “astronomical”, then the order of a million years or more, both on time scales “human”, for several months until a few decades.
