(71556) Page is an asteroid of the main belt , which on 27 February 2000 by the American astronomer David S. Dixon at Jornada Observatory (IAU code 715) in Las Cruces , New Mexico 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.
It was named on May 4, 2004 in honor of the American physicist and astrophysicist Gary L. Page of George Mason University in Fairfax , Virginia , who researched the existence and effects of non-baryonic matter within the solar system .
