- King Y (the LTO's Al-Tusi) was also photographed on color Hasselblad film, such as Apollo 16's frames AS16-120-19265 (near the frame's lower left corner), 19266 (left of frame's centre), 19267 (near the frame's upper left corner), and 19273 (central).

- This farside satellite feature of King was given its present name by Ewen Whitaker in NASA RP-1097 (1982). However, it had previously been given the distinctive name of Al-Tusi when, in 1976, the IAU approved that provisional name for the crater at 7.0 N, 120.0 W "as assigned", presumably on LTO-65C1 and LTO-65D2 (IAU Transactions XVIB). Al-Tusi was also incorporated into several minor feature names introduced on Topophotomap 65D2(S1). However, as Whitaker notes in his list of invalid names, the "Al-Tusi" mentioned in the IAU citation is the same person as the one already honored by the nearside crater Nasireddin. The name Al-Tusi (for the farside features) seems to have been dropped, for that name does not appear in the on-line IAU Planetary Gazetteer. But since there is no further mention of it in the IAU Transactions, exactly when and where it was dropped is unclear. Whitaker's own system of lettered craters for the farside (as published in NASA RP-1097) was adopted by the IAU in 2006 (IAU Transactions XXVI). - Jim Mosher
