3D convex shape model of Dido

Dido (minor planet designation: 209 Dido) is a main-belt asteroid with a diameter of Шаблон:Val.[1] 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 Шаблон:Val with an eccentricity (ovalness) of 0.058 and a period of Шаблон:Cvt. The orbital plane is tilted at an angle of 7.2° to the plane of the ecliptic.[1]

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 Шаблон:Val hours with a brightness variation of Шаблон:Val in magnitude.[2] The pole orientation in ecliptic coordinates, as determined from multiple light curve studies, is (βp, λp) = (Шаблон:Val, Шаблон:Val).[3]

209 Dido has been observed to occult 4 stars between 2005 and 2023.
