Rosa (minor planet designation: 223 Rosa) is a large Themistian asteroid. It is classified as a combination of C-type and P-type asteroids, so it is probably composed of carbonaceous material rich in water ice. It was discovered by Johann Palisa on 9 March 1882, in Vienna. The origin of the name is not known.
Photometric observations made in 2011–2012 at the Organ Mesa Observatory in Las Cruces, New Mexico, produced a light curve with a period of 20.283 ± 0.002 hours and a brightness variation of 0.13 ± 0.02 in magnitude. The curve has two asymmetrical maxima and minima per 20.283-hour cycle.[4]
The spacecraft JUICE is planned to pass through the asteroid belt twice, and a flyby of 223 Rosa has been proposed. If selected, JUICE would make its nearest approach on 15 October 2029.[2]
