( 8598 ) Tetrix is ​​an asteroid of the outer main belt, which was discovered on 29 September 1973 by the Dutch astronomer Cornelis Johannes van Houten couple and Ingrid van Houten - Groeneveld. The discovery happened during the 2nd Trojan survey, in which the 120 - cm Oschin Schmidt telescope at Palomar Observatory recorded by Tom Gehrels field plates at Leiden University were screened, 13 years after the beginning of the Palomar - Leiden Surveys. An unconfirmed sighting (1970 EB3 ) of the asteroid, there had been already on October 3, 1970 at the Observatorio Chilean Cerro El Roble.

The asteroid is part of the Themis family, a group of asteroids, which was named after ( 24) Themis. After FORMING classification (Small Main -Belt Asteroid Spectroscopic Survey) were assumed in ( 8598 ) Tetrix of a dark surface with a spectroscopic investigation of Gianluca Masi, Sergio Foglia and Richard P. Binzel, it might be so, roughly speaking, to act a C- asteroids.

The orbital inclination of ( 8598 ) Tetrix is low with 0.55 °, it is the plane of Earth's orbit around the Sun -like than the path of the other seven planets. The timeless ( nichtoskulierenden ) orbital elements of ( 8598 ) Tetrix are almost identical to those of the two smaller, if we start from the absolute brightness of 16.9 and 16.4 compared with 13.6, asteroid ( 300164 ) 2006 VE140 and ( 348 958 ) 2006 UO26.

( 8598 ) Tetrix is named after the black grouse, whose scientific name Tetra tetrix tetrix or Lyrurus is. At the time of designation of the asteroid on February 2, 1999, the black grouse was on the Dutch and European Red List of Threatened Species. The first letter of the asteroid ( 8585 ) to ( 8600 ) form the phrase Per aspera ad astra.
