Haworth is an impact crater that lies at the south pole region of the Moon. The crater is named after British chemist Walter Haworth.
Formation
According to a 2015 study by Tye et al., Haworth was formed sometime during the Pre-Nectarian period, meaning it is at least 3.9 Ga (billion years) old.{{cite journal|url=https://www.sciencedirect.com/science/article/abs/pii/S0019103515001165|title=The age of lunar south circumpolar craters Haworth, Shoemaker, Faustini, and Shackleton: Implications for regional geology, surface processes, and volatile sequestration|journal=Icarus|last1=Tye|first1=Alexander R.|display-authors=et al|date=15 July 2015|accessdate=September 2, 2022|volume=255|pages=70–77|doi=10.1016/j.icarus.2015.03.016|publisher=Elsevier|bibcode=2015Icar..255...70T |hdl=2060/20150006822|hdl-access=free}}
Physical features
Due to Haworth's position near the lunar south pole, large amounts of the crater are permanently shadowed regions. These regions are very cold; many are believed to never reach temperatures above 40 Kelvin, making Haworth colder than nearby craters such as Shackleton and Faustini.{{cite web|url=https://www.lpi.usra.edu/meetings/lpsc2013/eposter/2617.pdf|title=Thermal Extremes in Permanently Shadowed Regions at the Lunar South Pole|work=Jet Propulsion Laboratory|publisher=NASA & UCLA|date=2013|accessdate=September 2, 2022|last1=Sefton-Nash|first1=Elliott|last2=Seigler|first2=Matthew A.|last3=Paige|first3=David A.}} Haworth and its surrounding low-lying areas are home to frost, which may be partly caused by these particularly low temperatures.{{cite journal|title=Lunar water migration in the interval between large impacts: Heterogeneous delivery to Permanently Shadowed Regions, fractionation, and diffusive barriers|journal=Journal of Geophysical Research: Planets|date=16 December 2015|doi=10.1002/2015JE004929|pages=46–60|volume=121|issue=1|last1=Moores|first1=John E.|publisher=American Geophysical Union|s2cid=131734382 |doi-access=free}}
