In August 1877, American astronomer Asaph Hall discovered both of Mars' moons within days of each other, naming them Phobos (Fear) and Deimos (Dread) after the sons of the god Ares. Observed through the US Naval Observatory's powerful refractor telescope, these tiny irregular moons were unlike anything previously known. Their discovery expanded understanding of planetary systems and inspired poets and writers captivated by the mythology of Mars.

The discovery of Phobos and Deimos in 1877 added Martian satellites to planetary lore, influencing late Victorian literature. Poets like H.G. Wells incorporated these celestial bodies into their narratives, reflecting humanity's fascination with space and the unknown, and inspiring a sense of wonder about the cosmos.
