(27896) Tourminator is an asteroid of the main outer belt that was discovered on July 13, 1996 by the Slovak astronomers Adrián Galád and Alexander Pravda with the 60 cm reflector telescope of the Modra Observatory ( IAU code 118) of the Comenius University Bratislava in Modra has been 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. The timeless (non- osculating ) orbital elements of (27896) Tourminator are almost identical to those of the similarly sized (assuming the absolute brightness , which is between 14.1 and 14.7) asteroids (23385) 5168 T-2 , (33469) 1999 FL 36 , (43515) 2001 DS 11 , (72376) 2001 CY 6 and (133310) 2003 SO 57 .
According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic investigation by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (27896) Tourminator assumed a dark surface, so it could, roughly speaking, be around trade a C asteroid . However, this would rather not correspond to the members of the Eos family.
(27896) Tourminator was named on October 8, 2014 after the Slovak cyclist Peter Sagan (* 1990). Tourminator is one of Sagan's nicknames. The asteroid of the inner main belt (2709) Sagan, however, was named after Carl Sagan as early as 1982 .
