(IAU Directions) NASIREDDIN.--A somewhat smaller ring-plain on the S. of Miller, and of a very similar type. It contains a central peak and several minor elevations. Between its N.E. border and the S.E. flank of Miller is a smaller ring-plain of about half the size of Nasireddin, and on the S.W. a large enclosure named Huggins.

- Named for Nasir-Al-Din (Mohammed Ibn Hassan) (February 18, 1201 – June 26, 1274), a Persian philosopher, mathematician, astronomer, theologian, physician, and a prolific polymath writer. Nasir-Al-Din convinced Hulegu Khan to construct an observatory for establishing accurate astronomical tables for better astrological predictions. He was perhaps the first to treat trigonometry as a separate mathematical discipline.
- According to Whitaker (p. 219), this name was introduced by Mädler.
- In 1976, the IAU briefly approved the provisional name "Al-Tusi" for the completely unrelated farside crater currently known as King Y (IAU Transactions XVIB). The "Al-Tusi" mentioned in that IAU citation turns out to be the same person as the "Nasireddin" honored here, and the name Al-Tusi (for the farside feature) seems to have been quietly dropped. - Jim Mosher
- The LPI feature overlays in their Lunar Orbiter Digital Atlas are generally a reliable guide to the IAU nomenclature; but Nasireddin is mis-labeled as "Huggins" in their overlay for IV-107-H2. The 76-km crater identified there as Nasireddin is actually Stöfler J. Nasireddin is correctly identified on their overlay for IV-112-H2.
