Why do all the planets of the solar system and most of the satellites of the planets have direct motion, i.e., coinciding in direction with the rotation of the central body, while the most distant satellites of Jupiter have reverse motion?
The direct movement of planets and satellites indicates their genetic relationship with the central body. The reverse motion of satellites indicates the capture of these bodies from near-planetary space. Some of the distant satellites of the giant planets have such a motion: the satellites of Jupiter (Ananke, Karma, Pasiphae, Sinope), the satellite of Saturn (Phoebe) and the satellite of Neptune (Triton). It is possible that these satellites are asteroids captured by the planets.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
