Kepler crater -

The German astronomer and mathematician Johannes Kepler (1571–1630), a key figure in the 17th-century Scientific Revolution, is the individual for whom this crater is named for. It's a relatively small lunar impact site, just 32 m (19 mi) in diameter.

Langrenus crater -

Flemish astronomer Michael van Langren (1598–1675), the first person to draw a lunar map while giving names to many of the features, named the Langrenus crater after himself, which has an impressive diameter of 132 km (82 mi).

Archimedes crater -

The 81 km- (50 mi-) diameter Archimedes crater is named in honor of the ancient Greek scientist and astronomer Archimedes (c. 287–c. 212 BCE).

Tsiolkovsky crater -

The huge lunar impact crater known as Tsiolkovsky owes its name to Russian scientist Konstantin Tsiolkovsky (1857–1935). Located on the far side of the Moon, Tsiolkovsky is 184 km (114 mi) in diameter.

Bailly crater -

French astronomer Jean Sylvain Bailly (1736–1793) is the man for whom the Bailly crater is named for. At 303 km (188 mi) in diameter, this is the largest crater on the near side of the Moon. Incidentally, Bailly lost his head during the French Revolution, guillotined during the Reign of Terror.

Fra Mauro crater -

The Fra Mauro crater formation is barely discernible and in fact today is identified as the worn remnant of a walled lunar plain. Ninety-five km (59 mi) in diameter, this age-old landscape is named after the Italian cartographer Fra Mauro (c.1400–1464), best known for the world map he drew up in 1450, which at the time was the most detailed in medieval cartography.

Humboldt crater -

At 199 km (123 mi) in diameter, Humboldt is another crater recognized for its expansive dimensions. It's named after Wilhelm von Humboldt (1767–1835), a Prussian philosopher who founded the Humboldt University of Berlin.

Deslandres crater -

The third-largest crater formation on the visible Moon, Deslandres measures 227 km (141 mi) in diameter. The crater is named for Henri Alexandre Deslandres (1853–1948), a French astronomer and director of the Meudon and Paris Observatories.

Petavius crater -

Boasting a diameter of 177 km (109 mi), Petavius is significant in that its top side displays a prominent rille system—long, narrow depressions in the surface of the Moon that resemble channels that help accentuate the crater's broad dimensions. Petavius is named for French Jesuit theologian Denis Pétau (1583–1652), also known as Dionysius Petavius.

Stadius crater -

An imaginative observer might picture the surface of Stadius as having been trodden over by a cat. In fact, the remnants of this crater have been nearly obliterated by basaltic lava flows. Sixty-nine km (42 mi) in diameter, it's named after the Flemish astronomer and astrologer Johannes Stadius (1527–1579).

Metius crater -

The eponym for this 88 km- (54 mi) diameter crater is the Dutch geometer and astronomer Adriaan Adriaanszoon (1571–1635), who went by the name of Metius. The name "Metius" comes from the Dutch word meten, which means to measure or survey.

Stöfler and Faraday craters -

Stöffler is named after German mathematician Johannes Stöffler (1452–1531). Faraday, meanwhile, has overlain and damaged its western rim. This crater is named for the English scientist Michael Faraday (1791–1867), best known for his work on electricity and electrochemistry. Stöfler's diameter, by the way, measures around 126 km (78 mi).
