(IAU Directions) ANAXAGORAS.--A brilliant ring-plain of regular form, 32 miles in diameter, adjoining Goldschmidt on the W. It is a prominent centre of light streaks, some of which traverse the interior of Goldschmidt. On the north a peak rises to the height of 10,000 feet. There is a long ridge on the floor, running from W. to E.

Nomenclature
- Named for Anaxagoras (ca. 500 BC–428 BC), a pre-Socratic Greek philosopher and astronomer. He brought philosophy and the spirit of scientific inquiry from Ionia to Athens. His observations of the celestial bodies and the fall of meteorites led him to form new theories of the universal order. He attempted to give a scientific account of eclipses, meteors, rainbows and the sun.
