144 Vibilia is a carbonaceous asteroid from the central region of the asteroid belt, approximately 140 kilometers in diameter. It was discovered on 3 June 1875, by German–American astronomer Christian Peters at Litchfield Observatory of the Hamilton College in Clinton, New York, United States. Peters named it after Vibilia, the Roman goddess of traveling, because he had recently returned from a journey across the world to observe the transit of Venus. Peters also discovered 145 Adeona on the same night. The official naming citation was published by Paul Herget in The Names of the Minor Planets in 1955 (H 19).
