Aegle (minor planet designation: 96 Aegle) is a carbonaceous asteroid and the namesake of the Aegle family located in the outer regions of the asteroid belt, approximately 170 kilometers (110 miles) in diameter. It was discovered on 17 February 1868, by French astronomer Jérôme Coggia at the Marseille Observatory in southeastern France.[1] The rare T-type asteroid has a rotation period of 13.8 hours and has been observed several times during occultation events.[6] It was named after Aegle ("brightness"), one of the Hesperides (nymphs of the evening) from Greek mythology.[4][a]
