The Sun DOES rotate. See related question.
Please be more specific about which solar system.
Every member of the solar system revolves around some other member in an elliptical orbit. From time to time, other bodies ... such as non-periodic comets for example ... pass through the solar system and continue on their way. Those are not members of the solar system, just visitors.
