After reading http://www.astronomy.com/news/2013/...by-double-star-fomalhaut-is-actually-a-triple I began to wonder if the starmap would a) have fomalhaut show as a double or triple system and b) if they would alter the starmap every so often once better info like this becomes available so that the starmap remains as accurate as possible. If so how often should they update it or should it just remain as is due to issues with continuity?
