Answer:
For the name of Esther, a number of etymologies are possible.
1) Esther comes from the Persian "setareh," meaning "star".
2) Esther comes from the Aramaic "istahar," meaning "moon." Beautiful as the moon (Talmud, Megillah 13a).
3) Esther comes from the Semitic root aθtar (ath-tar), "morning star." There is support for this too in the Talmud (Yoma 29a).
4) Esther comes from the Median "astra," meaning "myrtle." The book of Esther (2:7) states that she had both names, Esther and Myrtle (Hadassah in Hebrew).
Theologically, the Book of Esther is unimportant, as it never even mentions God*. Historically it is also unimportant because scholars say that it contains so many historical errors that it can scarcely be based on fact. It is however, important to many Jews, because it provides evidence of the superiority in so many ways of the Jewish people in Babylon over their gentile rivals. Martin Luther complained that the book lionises the Jews too much.
Queen Esther has no particular relevance outside the Book of Esther.
Footnote
* The Latin Vulgate contains additional material that mentions God, and which Jerome acknowledged as late, Christian interpolations.
