The deepest point, also referred to as Litke Deep, is {{Convert|5,449|m|ft|abbr=on}} below sea level. It is the closest point of the upper surface of Earth's lithosphere to Earth's center, with Challenger Deep being {{cvt|14.7268|km|mi|1}} further from Earth's centre at a bathymetric depth of {{cvt|6,366.4311|km|mi|1}}.{{cite web|url=https://www.ripublication.com/ijome22/ijomev12n1_03.pdf |title=Revisiting "Ocean Depth closest to the Center of the Earth"|publisher= Arjun Tan, Department of Physics, Alabama A & M University|language=English|accessdate=18 September 2022}}

The deepest point in Litke Deep is the closest point on the Earth's surface to the Earth's center given that it is located along the planet's polar flattening. Based on average global sea level (mean sea level), the deepest point in Litke Deep is shallower than Challenger Deep.{{cite journal | url=https://www.ripublication.com/ijome22/ijomev12n1_03.pdf | title=Revisiting "Ocean Depth closest to the Center of the Earth" | last=Tan | first =Arjun | journal=International Journal of Mathematical Education | date=2022 | volume=12 | issue=1 | pages=11–15 | issn=0973-6948}} Litke Deep is the second deepest point in the Arctic Ocean after Molloy Deep.{{Cite journal|last1=Klenke|first1=Martin|last2=Schenke|first2=Hans Werner|date=2002-07-01|title=A new bathymetric model for the central Fram Strait|url=https://www.researchgate.net/publication/226884194|journal=Marine Geophysical Researches|volume=23|issue=4|pages=367–378|doi=10.1023/A:1025764206736|s2cid=128515547}}{{Cite journal|last1=Bourke|first1=Robert|last2=Tunnicliffe|first2=Mark|last3=Newton|first3=John|last4=Paquette|first4=Robert|last5=Manley|first5=Tom|date=1987-06-30|title=Eddy near the Molloy Deep revisited|url=https://www.researchgate.net/publication/252570235|journal=Journal of Geophysical Research|volume=92|pages=6773–6776|doi=10.1029/JC092iC07p06773}}{{Cite journal|last1=Thiede|first1=Jörn|last2=Pfirman|first2=Stephanie|author-link2=Stephanie Pfirman|last3=Schenke|first3=Hans Werner|last4=Reil|first4=Wolfgang|date=1990-08-01|title=Bathymetry of Molloy Deep: Fram Strait between Svalbard and Greenland|url=https://www.researchgate.net/publication/225753449|journal=Mar.
