Notes on Different Meanings

• The word has two distinct, unrelated referents: a historical figure and an astronomical feature. The lunar crater was named in honor of the astronomer Aristarchus of Samos (c. 310–230 BC), who proposed a heliocentric model. However, the dictionary entry provided specifically refers to the grammarian and the crater named after the astronomer, creating a common point of reference in the name "Aristarchus." Context always clarifies which is intended.
