(3054) Strugatskia is an asteroid of the main outer belt . It was discovered on September 11, 1977 by the Soviet astronomer Nikolai Tschernych at the Crimean Observatory in Nautschnyj ( IAU code 095). The asteroid had already been sighted: on October 16, 1928 under the provisional designation 1928 UC at the State Observatory in Heidelberg-Königstuhl and on May 2, 1959 (1959 JQ), July 21, 1960 (1960 OE) and April 4, 1961 (1961 VG) at the Goethe Link Observatory in Indiana .
The mean diameter of the asteroid was calculated to be 26.921 (± 0.205) km . The albedo of 0.056 (± 0.009) suggests a dark surface. According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel subdivided all investigated asteroids into C, S and V types (3054) Strugatskia assigned to the C asteroids .
The asteroid belongs to the Themis family, a group of asteroids named after (24) Themis . The timeless (not osculating ) orbital elements of (3054) Strugatzski are almost identical to those of five smaller asteroids: (74364) 1998 WZ 26 , (83914) 2001 VA 7 , (132925) 2002 SO 49 , (172782) 2004 EZ 75 and (193067) 2000 GZ 13 .
(3054) Strugatskia was named on July 2, 1985 after the Soviet science fiction authors Arkadi and Boris Strugazki .
