35 Leukothea is a large, dark asteroid from the asteroid belt. It was discovered by German astronomer Karl Theodor Robert Luther on April 19, 1855,<ref name="IAU_MPC"/> and named after Leukothea, a sea goddess in Greek mythology. Its historical symbol was a pharos (ancient lighthouse); it was encoded in Unicode 17.0 as U+1CED0 𜻐 (File:Leukothea symbol (fixed width).svg).<ref name=astunicode>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="Unicode-1CEC0">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Leukothea is a C-type asteroid in the Tholen classification system,<ref name=jpl/> suggesting a carbonaceous composition. It is orbiting the Sun with a period of Template:Convert and has a cross-sectional size of 103.1 km.

Photometric observations of this asteroid from the Organ Mesa Observatory in Las Cruces, New Mexico during 2010 gave a light curve with a rotation period of Template:Val hours and a brightness variability of Template:Val in magnitude. This is consistent with previous studies in 1990 and 2008.<ref name="Pilcher2010"/>

The computed Lyapunov time for this asteroid is 20,000 years, indicating that it occupies a chaotic orbit that will change randomly over time because of gravitational perturbations of the planets.<ref name="Sidlichovsky"/>
