::(36) Atalante



{{#invoke:Infobox|infobox}} 36 Atalante {{#invoke:IPAc-en|main}} is a large, dark main-belt asteroid. It was discovered by the German-French astronomer H. Goldschmidt on October 5, 1855, and named by French mathematician Urbain Le Verrier after the Greek mythological heroine Atalanta (of which Atalante is the German form).<ref name=schmadel2003/> The asteroid is also classified as a C-type one, according to the Tholen classification system.<ref name=jpldata/>

Observation of the asteroid light curve indicates it is rotating with a period of 9.93 ± 0.01 hours. During this interval, the magnitude varies by an amplitude of 0.12 ± 0.02.<ref name=mpb34_3_58/> By combining the results of multiple light curves, the approximate ellipsoidal shape of the object can be estimated. It appears to be slightly elongated, being about 28.2% longer along one axis compared to the other two.<ref name=aaas131_385/> Atalante was observed by Arecibo radar in October 2010.<ref name="Arecibo">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="detected">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

This asteroid shares a mean-motion resonance with the planets Jupiter and Saturn. The computed Lyapunov time for this asteroid is only 4,000 years, indicating that it occupies a highly chaotic orbit that will change randomly over time because of gravitational perturbations of the planets. This is the shortest Lyapunov time of the first 100 named asteroids.<ref name="Sidlichovsky"/>
