3552 Don Quixote, provisionally designated 1983 SA, is an exceptionally eccentric asteroid, classified as a near-Earth object of the Amor group, Mars-crosser and Jupiter-crosser, as well as a weakly active comet.

Discovery and naming

The asteroid was discovered on 26 September 1983, by Swiss astronomer Paul Wild at Zimmerwald Observatory near Bern, Switzerland.[6] It was named after the comic knight who is the eponymous hero of Cervantes' Spain novel Don Quixote (1605).[2] The approved naming citation was published by the Minor Planet Center on 2 December 1990 (M.P.C. 17466).[7]

Orbit and characteristics

Don Quixote is characterized as a dark D-type asteroid in the Tholen and SMASS taxonomy.[1]

It has a highly inclined comet-like orbit of 31 degrees that leads to frequent perturbations by Jupiter.[8] Don Quixote measures 18.4 kilometres in diameter and has a rotation period of 7.7 hours.[1][4]

Don Quixote by Spitzer Space Telescope, featuring its coma and tail.

Due to its comet-like orbit and albedo, Don Quixote has been suspected to be an extinct comet.[9] However, infrared observations with the Spitzer Space Telescope at 4.5 μm revealed a faint coma and tail around the object.[4] The cometary activity is inferred by carbon dioxide (CO
2
) molecular band emission. In March 2018 a tail was observed at visible wavelengths for the first time.[10] The observation of cometary features during two apparitions suggests that cometary activity is recurrent and Don Quixote is most likely a weakly active comet.[11]
