Haworth (crater) explained
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.[1]
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.[2] Haworth and its surrounding low-lying areas are home to frost, which may be partly caused by these particularly low temperatures.[3]
