(2052) Tamriko is an asteroid of the main belt , which on 24 October 1976 by Richard Martin West at La Silla Observatory ( IAU code 809) of the European Southern Observatory in Chile was discovered.
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.
designation
The asteroid was named after Tamara West, wife of Richard Martin West.
