(6897) Tabei is an asteroid of the inner main belt , which was discovered on November 15, 1987 by the Czech astronomer Antonín Mrkos at the Kleť observatory ( IAU code 046) near Český Krumlov .
The asteroid belongs to the Nysa group, a group of asteroids named after (44) Nysa (also called the Hertha family, after (135) Hertha ). The timeless (non- osculating ) orbital elements of (6897) Tabei are almost identical to those of the two smaller ones, assuming the absolute magnitude of 16.6 and 17.2 compared to 14.0, asteroids (173253) 1999 RQ 93 and ( 327186) 2005 LC 42 .
The mean diameter of the asteroid is around 4.5 km . The light curve of (6897) Tabei was examined on January 28 and 29, 2003 by William H. Ryan at the Vatican Advanced Technology Telescope in Arizona . The rotation period was determined to be 5.862 (± 0.001) h .
(6897) Tabei is named after the Japanese mountaineer Junko Tabei , who on May 16, 1975 became the first woman to reach the summit of Mount Everest . It was named on the proposal of the Czech astronomer Miloš Tichý by the International Astronomical Union (IAU) on May 23, 2000. Also after Junko Tabei, a mountain range in the southern hemisphere of the dwarf planet Pluto was named on November 19, 2019 : Tabei Montes .
