The Moon was very important for the geological evolution of the Earth, as it allowed our planet to slow down its rotation and reduce the number of meteorite impacts (this process will not last forever). However, the other planets also have satellites.
Mars, for example, has two small moons, Phobos e Deimoswhich from a morphological and dimensional point of view actually resemble two small asteroids more than moons. Probably attracted by the red planet, following some particular catastrophic event, scientists believe that Phobos and Deimos actually come from the asteroid belt.
However, how many satellites do the large gas giants of the external solar system have? Although it may seem like a banal question, in truth this question is among the most long-standing (and among the most difficult to answer) in modern astronomy.
Even though almost 500 years have passed since Galileo Galilei first observed Jovian satellites and several space missions have been carried out in the direction of the gas planets, it is still very difficult to quantify the precise number of satellites present in the solar system.
The reasons are simple. Gas giants are so far away that it is very difficult to study them from the surface of Earth, and they may also have moons so small that they are not detectable by probes and satellites.
Currently, the International Astronomical Union officially recognizes 238 moons around the 8 planets of our system, but if we take into account the data of the NASAwhich scoured the orbits of the planets in search of new moons (even those only a few kilometers large), would be 473 “small” satellites of our system.
Most of them can be found around the orbit of Jupiter and Saturn, which respectively are the first and second planets with the most moons.
Saturn has 83 satellites, while Jupiter has 92. However, if we also take into consideration the smaller bodies (satellites of a few km in diameter) it is the ringed planet is the planet with the most celestial bodies around its orbit, even without considering its ring dust system.
