Named in memory of a well-known authority on celestial mechanics, Evgenij Petrovich Aksenov (1933–1995), director of the Sternberg Astronomical Institute in Moscow for many years. With Grebenikov and Demin {see planets  (4268) and  (5086), respectively}, he investigated and found a general solution for the generalized problem of two fixed centers, carrying out a qualitative investigation of all possible types of motion within the problem and considering their stability. He also developed an analytical theory for the motions of artificial satellites based on a non-Keplerian intermediate orbit, and he proved the existence of several new classes of periodic solutions within the circular restricted three-body problem.
