(3357) Tolstikov is an asteroid of the outer main belt , which was discovered on March 21, 1984 by the Czech astronomer Antonín Mrkos at the Kle Observ Observatory ( IAU code 046) near Český Krumlov .
The asteroid belongs to the Eos family , a group of asteroids which typically have large semiaxes from 2.95 to 3.1 AU , bounded inward by the Kirkwood gap of the 7: 3 resonance with Jupiter , and orbital inclinations between 8 ° and 12 °. The group is named after the asteroid (221) Eos . The family is believed to have emerged from a collision more than a billion years ago. According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (3357) Tolstikov assumes a bright surface, so it could, roughly speaking, be around trade an S asteroid .
(3357) Tolstikov is named after the Soviet polar explorer Yevgeny Tolstikov . Antonín Mrkos had participated in the International Geophysical Year 1957/58 in the 3rd Soviet Antarctic Expedition, which was under the direction of Tostikov. Mrkos and Tostikow had worked together for a total of three years in the Mirny station on the Antarctic coast of the Davissee . The name was given by the International Astronomical Union (IAU) on February 26, 1994.
