48 Doris is one of the largest main belt asteroids. It was discovered on 19 September 1857 by Hermann Goldschmidt from his balcony in Paris.
To find a name for the object, Jacques Babinet of the Academy of Sciences created a shortlist and asked the geologist Élie de Beaumont to make the selection. De Beaumont chose Doris, after an Oceanid in Greek mythology. Since Doris was discovered on the same night as 49 Pales, de Beaumont suggested naming the two "The Twins".<ref>Template:Cite book</ref>
Physical characteristicsEdit
An occultation on 19 March 1981 suggested a diameter of 219±25 km.<ref name=Dunham>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Observations of an occultation on 14 October 1999, using four well-placed chords, indicate an ellipsoid of 278×142 km and that 48 Doris is an extremely irregularly shaped object.<ref name=RASNZ>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Doris will pass within 0.019 AU of Pallas in June 2132.<ref name=jpl-close>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
