Encyclopedic overview
Bebhionn (/ˈbeɪvɪn/), also known as Saturn XXXVII, is a small, irregular natural satellite of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt, Jan Kleyna, and Brian G. Marsden on 4 May 2005 from observations taken between 12 December 2004 and 9 March 2005.
Bebhionn is about 6 kilometres in diameter and orbits Saturn at an average distance of 16,898 Mm in 820.130 days at an inclination of 41° to the ecliptic (18° to Saturn's equator) and with an eccentricity of 0.469. The rotation period of Bebhionn was measured at 16.33±0.03 hours by the ISS camera of the Cassini spacecraft. Bebhionn's light curve reflects an elongated shape with large variations in brightness, making it a leading candidate for a contact binary or binary moon.
