Bianchini (lunar crater)

Bianchini is a lunar impact crater that lies along the northern Jura Mountains that ring the Sinus Iridum,^[3] in the northwestern part of the near side of the Moon. The impact of this crater near the edge of the Jura Mountains deposited some material into the Sinus Iridum floor.^[4]

On the lunar geologic timescale, Bianchini dates to the Upper (Late) Imbrian age.^[2] The polygonal rim of this crater is not significantly worn, although there is a small crater along the inner side of the eastern rim. Within the inner wall is a somewhat irregular floor and a small cluster of ridges at the midpoint. Portions of the inner wall have slumped toward the floor along the northern edges.^{[5][6][7]: 11}

This crater was named after Italian astronomer Francesco Bianchini (1662-1729).^[1] The name was incorporated into lunar nomenclature by the Italian astronomer Giovanni Riccioli in 1651 as 'Bianchinus'.^[8] Its modern designation was formally adopted by the International Astronomical Union in 1935.^[1]
