(6992) Minano-machi is an asteroid of the main belt , which on 27 January 1995 by Japanese amateur astronomer Takao Kobayashi at Oizumi Observatory ( IAU code 411) in the Japanese prefecture of Gunma was discovered.
The asteroid was named on January 6, 2003 after the city of Minano-machi , located in Saitama Prefecture on the main island of Honshu .
The celestial body belongs to the Eos family, a group of asteroids, which typically have large semi-axes 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.
