(35) Leukothea is an asteroid of the main asteroid belt that was discovered on April 19, 1855 by Karl Theodor Robert Luther at the Düsseldorf observatory .
The celestial body was named after Leukothea , a sea goddess who saved Odysseus from drowning.
Leukothea moves at a distance of 2.3211 ( perihelion ) to 3.6689 ( aphelion ) astronomical units around the sun in 5.184 years . The orbit is inclined 7.929 ° to the ecliptic , the orbital eccentricity is 0.225.
Based on the absolute brightness of 8.5 and an albedo of 0.066 typical for asteroids with a dark, carbonaceous surface, a mean diameter of about 104 kilometers can be derived for Leukothea. This value is very uncertain due to the range of fluctuation in plausible albedo values. Due to the small size of Leukothea, an irregular shape is also to be expected, since the natural gravity for the formation of an ellipsoid of revolution should not be sufficient. Due to the fluctuations in brightness due to the rotation due to the irregular shape, a value of 32 hours was derived for one rotation around its own axis.
