Rosa (
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]
A flyby of Rosa by the
JUICE spacecraft, which is planned to pass through the asteroid belt twice, was proposed to occur on 15 October 2029.[2] However, the mission team ultimately decided against the proposed flyby to maximize fuel for the primary mission.[5]

We had been considering slightly diverting Juice to visit an asteroid en route to #Jupiter. To maximise fuel for our main mission (the tour around the gas giant and its icy moons), we have decided against this asteroid flyby" (Tweet) – via Twitter.
