Foucault is a small lunar impact crater that lies along the southern edge of Mare Frigoris, to the southeast of the crater Harpalus.
 In the rugged terrain to the south of Foucault is Sharp.
 The outer perimeter of Foucault forms a somewhat irregular circle, with slight outward bulges to the south and northeast.
 The inner wall of the rim is not notably terraced, and slopes down directly to the uneven floor.
 It is named after physicist Léon Foucault, most famous for the Foucault pendulum.
Colegio San Agustín – Makati (abbreviated as CSA or CSA-Makati) is a private, co-educational Catholic school conducted by the Order of Saint Augustine.
 It is located on Palm Avenue, Dasmariñas Village, Makati City, Philippines.
 While it is not the oldest Augustinian school in the Philippines named Colegio San Agustín (that distinction belongs to Colegio San Agustin-Bacolod), it is the most prominent and famous among its namesake.
 The school is one of the most diverse in the Philippines in terms of nationality, with 11% of the student population coming from over 40 countries.
Harpalus is a young lunar impact crater that lies on the Mare Frigoris, at the eastern edge of the Sinus Roris.
 To the southeast at the edge of the mare is the small crater Foucault, and to the northwest on the opposite edge is the walled plain named South.
Birmingham is the surviving remnant of a lunar crater.
 It is named after the astronomer John Birmingham (not, as is often stated, the British city nor its Alabama namesake).
Bouguer is a lunar impact crater that lies along the southern edge of the Mare Frigoris, to the north of the crater Bianchini.
 To the west-southwest of Bouguer, along the same shore of the mare, is the crater Foucault.
 Nearly due west is the more prominent Harpalus, and to the west is La Condamine.
Jean Bernard Léon Foucault (] ; 18 September 1819 – 11 February 1868) was a French physicist best known for his demonstration of the Foucault pendulum, a device demonstrating the effect of the Earth's rotation.
 He also made an early measurement of the speed of light, discovered eddy currents, and is credited with naming the gyroscope.
Vallis Baade is a 203 km long sinuous valley on the Moon running south-southeast from the crater Baade and centered at (south of the Montes Cordillera).
 It has the same namesake as the crater, the German astronomer Walter Baade.
Wolfgang Ludwig Krafft (25 August 1743 – 20 November 1814) was a German astronomer and physicist.
 He is the namesake of the lunar crater Krafft which has a diameter of 51 km.
Jacob Heinrich Wilhelm Lehmann (3 January 1800 – 17 July 1863) was a German astronomer.
 He is most noted today as the namesake for the crater Lehmann on the Moon.
