Description: Elger
([/IAU%20Directions IAU Directions]) PHILOLAUS.--A ring-plain 46 miles in diameter, on the N.W. of [/Fontenelle Fontenelle]. Its bright walls rise on the E. to a height of nearly 12,000 feet above the floor (on which there is a conspicuous central mountain), and exhibit many prominent terraces. Philolaus is partially encircled, at no great distance, by a curved ridge, on which will be found a number of small craters.

The crevasses on the floor of Philolaus
Philolaus is a crater which shows crevasses on its quite chaotic floor. In 2018, scientists discovered possible skylights in these crevasses.
See Bibliography below (the article from P. Lee).
Additional Information
- Depth data from [/Kurt%20Fisher%20crater%20depths Kurt Fisher database]
- Westfall, 2000: 3.68 km
- Viscardy, 1985: 3.4 km
- Cherrington, 1969: 3.29 km
- From the shadows in LO-IV-152H, the east wall of Philolaus is up to 3600 m above the floor. The southern central peak is at least 970 m tall. - JimMosher JimMosher
- Measures on LRO QuickMap give max depth about 4 km
- [/Central%20peak%20composition Central peak composition]: A & GNTA1 ([/Tompkins%20%26%20Pieters%2C%201999 Tompkins & Pieters, 1999])
- Central peak height
- Measures on LRO QuickMap give max peak height for ring of peaks at 1.0 k
- [/Sekiguchi%2C%201972 Sekiguchi, 1972] lists several internal peaks
- 1.2 km "Large mountain" slightly south and west of center
- 0.7 km and 0.5 km "Peaks standing on the north side of the [Large mountain]"
- 1.3 km measured from an easterly-falling shadow, "The highest peak standing on the easterly eccentric position."
- 0.2 km "A long dyke" to the north and east
- 0.4 km "A low hill at the bottom of the east wall" - fatastronomer fatastronomer
- [/Sekiguchi%2C%201972 Sekiguchi, 1972] lists several internal peaks
- Exterior impact melt deposits most extensive to NNW, max of ~35 km beyond rim. Most extensive ejecta, rays and secondary craters to the NE, with max wall slumping on W side of crater, and topographically lowest rim crest to NNW ([/Hawke%20and%20Head%2C%201977 Hawke and Head, 1977]).
- Included in [/ALPO%20list%20of%20bright%20ray%20craters ALPO list of bright ray craters]
- A row of low hills 120km east and south of Philolaus was measured via the shadow method and LTVT. A profile was produced with the highest point being slightly less than 250m (Boint, "Profiles Of Features In The J. Herschel Crater, Fontenelle Crater, and La Condamine Crater Area", Selenology Today, Vol. 9. 1-12.).- fatastronomer fatastronomer
- TSI = 35, CPI = 30, FI = 25; MI =90 [/Smith%20and%20Sanchez%2C%201973 Smith and Sanchez, 1973]
- Studying Philolaus on May 20, 1948, Richard M. Baum noted a reddish glow to the northeast, which he watched for fifteen minutes before it faded from sight. Source: Epic Moon, page 309. Perhaps interesting to know: in May 1948, Full Moon happened on the 23th, at 0:37 U.T., source: Fred Espenak's NASA Eclipse website, Phases of the Moon: 1901 to 2000- DannyCaes DannyCaes Jul 26, 2013
Nomenclature
- Philolaus of Croton; Greek mathematician, astronomer, philosopher (unkn-fl. 400 B.C.).
- Somewhere between Philolaus and the moon's limb (or: at the moon's limb) is a crater which was called Rhodes by [/Wilkins%20and%20Moore Wilkins and Moore], but the I.A.U. did not accept that name.
