[12] Two nights later, the body was independently discovered by Polish astronomers Jan Piegza and Tadeusz Banachiewicz at Cracow and Warsaw, respectively.
[11] In April 2004, a rotational lightcurve of Milankovitch was obtained from photometric observations by American amateur astronomer Walter R. Cooney Jr.
[9] In October 2006, French astronomer Pierre Antonini obtained another lightcurve, which gave a similar period of 11.63±0.03 and an amplitude of 0.14 magnitude (U=2).
[10] According to the space-based surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Milankovitch measures between 27.8 and 33.8 kilometers in diameter and its surface has an albedo between 0.142 and 0.235.
[3] This minor planet was named in memory of Serbian-Yugoslav scientist Milutin Milanković (1879–1958), best known for his Milankovitch cycles, a theory of celestial mechanics that describes the collective effects of changes in the Earth's movements upon its climate.
