222 Lucia is a large Themistian asteroid. It was discovered by Johann Palisa on February 9, 1882 in Vienna and named after Lucia, daughter of Austro-Hungarian explorer Graf Wilczek.
This object is spectral C-type and is probably composed of primitive carbonaceous material. Based upon analysis of infrared spectra, it has a diameter of 59.8 ± 0.8 km. This object belongs to the Themis family, which was formed by the break-up of a larger parent body about a billion years ago.[1]
