Wolf 359 might not appear in some digital star atlases due to several potential reasons. First, some star atlases may choose to focus primarily on brighter stars or objects that are more easily observed by amateur astronomers, as Wolf 359 is relatively dim and difficult to see without specialized equipment. Additionally, variations in the database or catalog each star atlas uses could affect whether a star like Wolf 359 is included. Lastly, it’s also possible that the atlas in question simply has an oversight or limitation in its database, leading to certain stars being omitted. For more specialized or detailed star databases or software, Wolf 359 is usually included due to its scientific significance as a nearby red dwarf star.
