solar neighborhood

(Milky Way in the vicinity of the Sun)

The phrase solar neighborhood, meaning the vicinity of space near the solar system is used informally and in research papers. It generally is meant to include nearby stars, possibly meaning a tiny part of the Milky Way and possibly meaning a more substantial portion, e.g., 5%. A research paper is likely to cite its criteria which could be as small as 10 parsecs radius to 1000 parsecs or more.
