'''Libussa''' ([[minor planet designation]]: '''264 Libussa''') is a [[Asteroid belt|Main belt]] [[asteroid]] that was discovered by [[Christian Heinrich Friedrich Peters|C. H. F. Peters]] on December 22, 1886, in [[Clinton, Oneida County, New York|Clinton, New York]] and was named after [[Libuše|Libussa]], the legendary founder of [[Prague]].<ref>{{cite book | chapter=(264) Libussa | title=Dictionary of Minor Planet Names – (264) Libussa | publisher=[[Springer Berlin Heidelberg]] | date=2007 | last=Schmadel | first=Lutz D. | page=38 | isbn=978-3-540-00238-3 | doi=10.1007/978-3-540-29925-7_265}}</ref> It is classified as an [[S-type asteroid]].

[[Photometry (astronomy)|Photometric]] observations of this asteroid at the Organ Mesa Observatory in [[Las Cruces, New Mexico]], in 2008 gave an asymmetrical, bimodal [[light curve]] with a period of 9.2276 ± 0.0002 hours and a brightness variation of 0.33 ± 0.03 in [[Magnitude (astronomy)|magnitude]].<ref name="Pilcher2009"/> Observation from the [[W. M. Keck Observatory]] show an [[angular size]] of 57 mas, which is close to the resolution limit of the instrument. The estimated maximum size of the asteroid is about 66 ± 7&nbsp;km. It has an asymmetrical shape with a size ratio of more than 1.22 between the major and minor axes.<ref name="Marchis2006"/>

Between 2005 and 2021, 264 Libussa has been observed to [[Occultation|occult]] five stars.
