8034 Akka, provisional designation 1992 LR, is a stony and eccentric asteroid, classified as near-Earth object and Apollo asteroid, about 0.7 kilometers in diameter. It was discovered by American astronomer couple Carolyn and Eugene Shoemaker at the U.S. Palomar Observatory, California, on 3 June 1992, as the asteroid neared a close approach to Earth the following month at 12 million kilometers.[1][7]
The S-type asteroid orbits the Sun at a distance of 1.1–2.6 AU once every 2 years and 6 months (904 days). Its orbit shows a high eccentricity of 0.41 and an inclination of 2 degrees from the plane of the ecliptic. With an Earth minimum orbit intersection distance (MOID) of 0.072 AU (11,000,000 km), it is only slightly above the threshold-limit of 0.05 AU, defined for potentially hazardous asteroids. The asteroid frequently makes close approaches to Earth and Mars. Its closest recorded approach to Earth and Mars is 0.081 AU on July 29, 1992 and 0.061 AU on April 26, 1982, respectively. It will make its closest approach to another planet when it comes within 0.044 AU of Mars on April 6, 2171.[1]
A photoelectic light-curve observation by Polish astronomer Wiesław Wiśniewski of the University of Arizona in 1992, gave a rotation period of 7.283±0.004 hours with a brightness amplitude of 0.46 in magnitude.[5] The Collaborative Asteroid Lightcurve Link (CALL) assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 0.7 kilometers.[3]
The minor planet was named after Akka from Finnish mythology. She is the Earth's mother, and the goddess of harvest and female sexuality. She symbolizes love, agriculture and womanliness. Akka is the wife of the supreme sky god Ukko, after whom the minor planet 2020 Ukko is named.[2]
