17473 Freddiemercury, provisional designation 1991 FM3, is a bright asteroid from the inner regions asteroid belt, approximately 3.4 kilometers in diameter. The asteroid was discovered on 21 March 1991, by Belgian astronomer Henri Debehogne at ESO's La Silla Observatory in northern Chile, and later named in memory of Freddie Mercury.[2]
Classification and orbit
Freddiemercury orbits the Sun in the inner main-belt at a distance of 2.0–2.8 AU once every 3 years and 8 months (1,350 days). Its orbit has an eccentricity of 0.16 and an inclination of 1° with respect to the ecliptic.[1]
The body's observation arc begins 9 years prior to its official discovery observation, with its identification as 1982 VC9 at Crimea–Nauchnij in November 1982.[2]
Physical characteristics
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Freddiemercury measures 3.4 kilometers in diameter and its surface has a high albedo of 0.313.[3]
As of 2017, the asteroid's composition, as well as its rotation period and shape remain unknown.[1][4]
Naming
On 4 September 2016, the day what would've been the day before Freddie Mercury's 70th birthday, the International Astronomical Union and the Minor Planet Center named it "Freddiemercury" after Freddie Mercury (1946–1991), as the asteroid was discovered in the year that the singer died (M.P.C. 101215)[5] and its provisional designation included his initials. The approved naming was announced by Brian May at Montreux Casino to mark the singer's 70th birthday.[6][7]
