- Depth data from Kurt Fisher database
- Westfall, 2000: 4.27 km
- Central peak composition: A (Tompkins & Pieters, 1999)
- Named for Fridtjof Nansen (1861-1930), a Norwegian explorer.
- Name originally proposed by P.Moore; shifted to a different crater in Rectified Lunar Atlas (1963) and approved by IAU in 1964 (Whitaker, p. 235).
- The much smaller astronaut-named feature Nansen-Apollo, at the Apollo 17 landing site, honors the same person.
- According to H. P. Wilkins and P. Moore's book The Moon there should be a limb-crater called Esquivel, beyond Nansen. The IAU did not accept the name Esquivel. Pedro Esquivel was a Spanish geographer (circa 1550).
Fridtjof Nansen in the Sourcebook Project (Rare Halos, Mirages, Anomalous Rainbows, and related electromagnetic phenomena, William R. Corliss, 1984):
- The Winter Night (Farthest North, 1897) (Optical Effects Where Halo Displays Touch the Horizon).
- We Prepare for the Sledge Expedition (Farthest North, 1897) (Unexplained Magnetic Disturbances).
