(11095) Havana is an asteroid of the main outer belt , which was discovered on August 12, 1994 by the Belgian astronomer Eric Walter Elst at the La Silla Observatory of the European Southern Observatory in Chile ( IAU code 809).
The mean diameter of the asteroid was calculated to be 10.211 (± 0.333) km . With an albedo of 0.081 (± 0.016) it has a dark surface. The rotation period of (11095) Havana was published in 2015 by Adam Waszczak, Chan-Kao Chang, Eran Ofek et al. examined. However, the light curve was not sufficient for a determination.
The asteroid belongs to the Themis family, a group of asteroids named after (24) Themis . According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (11095) Havana assumed a dark surface, so it could be roughly seen and appropriate to the Themis family to be a C asteroid .
The timeless (not osculating ) orbital elements of (11095) Havana are almost identical to those of the smaller asteroid (106909) 2000 YA 49 .
(11095) Havana was named after Havana on May 23, 2000 , the capital of the island state of Cuba .
