(11289) Frescobaldi is an asteroid of the outer main belt , which was discovered on August 2, 1991 by the Belgian astronomer Eric Walter Elst at the La Silla Observatory of the European Southern Observatory in Chile ( IAU code 809). There had already been several unconfirmed sightings of the asteroid: on December 18, 1976 under the provisional designation 1976 YP 5 at the Crimean Observatory in Nautschnyj and several times at the Karl Schwarzschild Observatory in the Tautenburg Forest , on January 12, 1988 (1988 AL 3 ), February 4, 1989 (1989 CS 6 ) and March 6, 1989 (1989 EP 7 ).
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 investigation by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (11289) Frescobaldi assumed a dark surface, so it could, roughly speaking, be around trade a C asteroid .
The timeless (non- osculating ) orbital elements of (11289) Frescobaldi are almost identical to those of the smaller, if one assumes the absolute brightness of 14.9 versus 13.3, asteroids (12969) 3482 T-3 .
(11289) Frescobaldi was named on March 2, 2000 after the Italian composer and organist Girolamo Frescobaldi (1583–1643). Frescobaldi, along with Jan Pieterszoon Sweelinck, is considered to be the most influential composer for keyboard instruments of the first half of the 17th century. The asteroid of the main outer belt (7621) was named Sweelinck after Sweelinck in 1997 .
