LO-IV-133H (Up) Milichius is the circular crater to the right of center. The 9-km diameter crater on the left is Milichius A, and the 4-km crater near the bottom is Milichius K. Neither the prominent dome to the west of Milichius, nor the less obvious one to its northwest, both of which have what appear to be volcanic caldera at their summits, have official IAU names, although the more prominent one was formerly known as Milichius Pi. (Bottom) A LRO version!
(IAU Directions) MILICHIUS.--Is situated on the N.N.W. of Hortensius. It is fully as bright, but rather smaller. Its floor, apparently devoid of detail, is considerably depressed below the surrounding surface.

- From the shadows in LO-IV-133H, Milichius is a little over 2500 m deep. - Jim Mosher
- Included in ALPO list of bright ray craters
- A low-albedo formation, like Mons Moro in Mare Cognitum, is detectable slightly west of Milichius K. See Lunar Orbiter IV's photograph 133H at the top of this page, and also the extreme close up of that formation in the LRO's ACT-REACT Quick Map, at coordinates LONG: -30.7, LAT: 8.6 - DannyCaes Jun 11, 2011
- Named for Jacob (Milich) Milichius (January 24, 1501 - November 10, 1559), a German doctor, mathematician, astronomer. He taught at Wittenberg, where he received an M.D. degree and became a professor of mathematics. Among his works was a 1535 commentary on the second book of Pliny.
- According to Whitaker (p. 213), this name appeared on Riccioli's map, however it was used to name the feature later known as Milichius Alpha (a peak about 65 km southeast of Milichius). Exactly who moved the name to the present crater is not clear. - Jim Mosher
- None of the domes near Milichius seem to have been named in the the original IAU nomenclature of Named Lunar Formations. The prominent one to the immediate west of Milichius was given the name Milichius Pi on chart SLC E4 of the System of Lunar Craters (1966); but the IAU dropped this name (along with nearly all other Greek-lettered names) in 1973, and it has not been officially renamed. - Jim Mosher. The elimination of many of the Greek-lettered identifications at domes and hillocks was one of the most unintelligent actions of the IAU. - DannyCaes Mar 14, 2016
- Quesada (a disallowed name from Van Langren for Milichius Gamma, see page 199 of E.A.Whitaker's Mapping and Naming the Moon).
