Isolda (
minor planet designation: 211 Isolda) is a very large, dark main-belt asteroid. It is classified as a C-type asteroid and is probably composed of primitive carbonaceous material. The spectra of the asteroid displays evidence of aqueous alteration.[6]
It was discovered by Austrian astronomer
Isolde, heroine of the legend of Tristan and Iseult.[7]
In 2001, the asteroid was detected by radar from the Arecibo Observatory at a distance of 1.78 AU. The resulting data yielded an effective diameter of 143 ± 16 km.[8]
Between 2009 and 2022, 211 Isolda has been observed to occult seven stars.[citation needed]
