(17473) Freddiemercury is an asteroid of the main inner belt discovered on March 21, 1991 by the Belgian astronomer Henri Debehogne at the La Silla Observatory of the European Southern Observatory in Chile ( IAU code 809). The asteroid had already been sighted on November 9, 1982 under the provisional designation 1982 VC 9 at the Crimean Observatory in Nautschnyj .
The asteroid is a member of the Massalia family, a group of asteroids with low orbital inclination named after their largest member (20) Massalia .
The mean diameter of the asteroid was calculated to be 3.435 (± 0.374) kilometers and the albedo to be 0.313 (± 0.064).
(17473) Freddiemercury was named on August 18, 2016 after the singer Freddie Mercury (1946-1991), at the suggestion of Joel Parker of the Southwest Research Institute , who wanted to honor Freddie Mercury on his 70th birthday. The International Astronomical Union (IAU) then selected the asteroid 1991 FM 3 because the initials Freddie Mercury are included in the provisional name. A designation certificate was issued by the IAU on September 4, 2016.
