Perseids

Part of speech: noun

Definitions

1. A meteor shower that occurs annually when Earth passes through the debris left by Comet Swift-Tuttle as it orbits the sun
2. It is named after the constellation Perseus, from which the meteors appear to radiate
3. Known for its bright meteors and often produces a significant number of visible shooting stars during its peak each August

Etymology: The name given to a well-known meteor shower, first recorded in the 19th century, derives from its apparent radiant point in the sky near the constellation Perseus. These shooting stars seem to emerge from this region, which links the event closely to the mythological figure Perseus, the Greek hero famed for slaying Medusa. The term itself is a modern coinage, created by adding the suffix "-ids," commonly used in astronomy to denote meteor showers, to the root Perseus. This practice of naming meteor showers after the constellation from which they appear to originate began in the 19th century as astronomers sought systematic ways to catalog and study these celestial phenomena. The shower results from Earth passing through the debris left by the comet Swift-Tuttle, a connection established through careful observation and orbital calculations in the 20th century. The meteors are particles from this comet burning up in Earth's atmosphere, but the name recalls the culture and mythology that humans have long projected onto the night sky. Thus, the term combines classical mythology with modern scientific naming conventions, bridging ancient stories and contemporary astronomy in a single, evocative word. The Perseids have become a popular annual event for skywatchers, their name a reminder of the deep historical roots of star lore.
