Schiaparelli ( SKAP-ə-REL-ee, SHAP-, US also skee-AHP-, Italian: [skjapaˈrɛlli]) is an impact crater on Mars, located near the planet's equator at latitude 3° south and longitude 344° in the Sinus Sabaeus quadrangle. It measures approximately 459 kilometers (285-miles) in diameter and was named after Italian astronomer Giovanni Schiaparelli, known for his observations of the Red Planet and his mistranslated term "canali". The name was adopted by IAU's Working Group for Planetary System Nomenclature in 1973. Source: Wikipedia (en)
