3D convex shape model of Dido
Dido (minor planet designation : 209 Dido ) is a main-belt asteroid with a diameter of 179± 1 km .[4] It was discovered by C. H. F. Peters on October 22, 1879, in Clinton, New York and was named after the mythical Carthaginian queen Dido . This asteroid is orbiting the Sun at a distance of 3.15 AU with an eccentricity (ovalness) of 0.058 and a period of 5.59 yr. The orbital plane is tilted at an angle of 7.2° to the plane of the ecliptic .[4]
209 Dido is classified as a C-type asteroid and is probably composed of carbonaceous materials. Like many asteroids of its type, it has an extremely low albedo . Photometric observations at the Palmer Divide Observatory during 2005 showed a rotation period of 5.7366± 0.0005 hours with a brightness variation of 0.17± 0.02in magnitude .[6] The pole orientation in ecliptic coordinates , as determined from multiple light curve studies, is (βp , λp ) = ( 120°± 6° , 66°± 7° ).[7]
209 Dido has been observed to occult 4 stars between 2005 and 2023.
