514107 Kaʻepaokaʻāwela (/kəˌʔɛpə.oʊkə.ʔɑːˈvɛlə/), provisionally designated 2015 BZ509 and nicknamed Bee-Zed,[9] is a small asteroid, approximately 3 km (2 mi) in diameter,[8] in a resonant, co-orbital motion with Jupiter.[3] It is an unusual minor planet in that its orbit is retrograde, which is opposite to the direction of most other bodies in the Solar System.[4] It was discovered on 26 November 2014, by astronomers of the Pan-STARRS survey at Haleakala Observatory on the island of Maui, United States.[1] Kaʻepaokaʻāwela is the first example of an asteroid in a 1:–1 resonance with any of the planets.[5] This type of resonance had only been studied a few years before the object's discovery.[10][11] One study suggests that it was an interstellar asteroid captured 4.5 billion years ago into an orbit around the Sun.
