- According to the Kaguya laser altimeter, the highest point on the Moon is on the shared rim of Engel'gardt and Engel'gardt B. This point is on the primary rim of the Dirichlet-Jackson Basin. The lowest point is on the floor of the farside crater Antoniadi.

Nomenclature
- Named for Vasilij Pavlovich Engel'gardt (1828-1915), a Russian astronomer.
- Engelhardt was in the list of IAU-approved farside names published in Menzel, 1971. The biographical information, supplied there by Prof. B. Levin, describes the honoree as a "Russian amateur astronomer [who] made numerous observations of comets, asteroids, nebulae, and star clusters from his private observatory in Dresden." Baron von Engelhardt (as he was known in Germany) published at least one book describing his astronomical observations.
- The IAU approved spelling was changed to Engel'gardt at some unknown later date. As with several other names of this sort, since the change was not documented it is unclear if the old spelling in parenthesis is regarded as part of the current official IAU name, or not.
- According to this map (1969) of the Sternberg Institute, there should be a crater east-northeast of Engel'gardt for which the name Wheatstone was proposed (lunar formation N° 747 in the accompanying nomenclature gazetteer). Slightly north of the above mentioned Wheatstone, there should be a crater for which the name Perevoshchikov was suggested (N° 587 on the same map). Neither of these names was adopted by the IAU.

Bibliography
- An Obituary notice for "B. P. Engelhardt" appears in JBAA, vol. 26, p. 39 (1915).
- According to the curator of the above-referenced site, noted astronomical historian Wolfgang Dick, "Basilius von Engelhardt" would be the German form of the Russian name "Vasily [or Vasilij] Engelgardt" which might explain the initials "B. P." Prof. Dick reports that Engelhardt was born in Russia and died Dresden and believes his ancestors were of German, rather than Russian, origin.
