The minor in astronomy consists of a minimum of 15 units (to include Astronomy 201) and 12 upper division units selected from Astronomy 301, 310, 320, 340, 350, 440, or 450.

Courses in the minor may not be counted toward the major, but may be used to satisfy preparation for the major and general education requirements, if applicable.  A minimum of six upper division units must be completed in residence at San Diego State University.
