Dear Branko,
Solitons are all elements of all levels of matter. All of them form gravispheres, which are potential wells. Neutrinos are usually called elements of the orbital electrons of the quark level of matter, which are, for example, elements of molecular bonds and which form orbital potential wells.
The function of the planets is to concentrate the energy of the environment of the physical vacuum in the star to minimize the energy of its interaction with high-speed flows of the environment. This function is similar to the function of electrons in an atom, to protect the nucleus from possible external disturbances.
The other solar system is different, for example, in the same way that the planetary system of Saturn is different from the planetary systems of Jupiter, Uranus, Neptune Mars, Venus and the Earth. Earth has one large satellite, unlike other planets. Universal quantum laws form many variants of gravispheres (potential wells), as well as many complex atoms.
Warm Regards,
Vladimir
