(11306) Åkesson is an asteroid located in the outer main belt . It was discovered on March 17, 1993 during the Uppsala-ESO Survey of Asteroids and Comets at the La Silla Observatory of the European Southern Observatory in Chile ( IAU code 809).
The mean diameter of the asteroid was calculated to be 8.715 (± 0.161) kilometers and the albedo to be 0.093 (± 0.016).
Mean solar distance ( major semi-axis ), eccentricity and inclination of the orbit plane of the asteroid roughly correspond to the Hygiea family, a rather older group of asteroids, as is suspected, the largest member of which is the asteroid (10) Hygiea .
(11306) Åkesson was named on July 26, 2010 after the Swedish poet and songwriter Sonja Åkesson (1926–1977).
