Lennon is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) in 2013. Lennon is named for the English singer and songwriter John Lennon (of The Beatles).
Lennon lies on the south rim of the ancient Lennon-Picasso Basin. To the east of Lennon is Bulsara. Together with crater Joplin, Lennon and Bulsara form a line of nearly equally spaced craters.[https://asc-planetarynames-data.s3.us-west-2.amazonaws.com/H-14.pdf Gazetteer of Planetary Nomenclature - Mercury H-14 quadragnle map]
