Quizplus · Accepted Answer

A parsec (pc) is a unit of distance used in astronomy to measure large distances to objects outside our solar system. 5.6 parsecs is equivalent to approximately 18.27 light-years, which is far beyond the scale of our solar system but well within the confines of our Milky Way galaxy. This makes a star the most likely candidate for an object at this distance.
