Kerberos is a small natural satellite of Pluto, about 19 km (12 mi) in its longest dimension. Kerberos is also the second-smallest moon of Pluto, after Styx. It was the fourth moon of Pluto to be discovered and its existence was announced on 20 July 2011.[1] It was imaged, along with Pluto and its four other moons, by the New Horizons spacecraft in July 2015.[9] The first image of Kerberos from the flyby was released to the public on 22 October 2015.[10]
