Florentina (
minor planet designation: 321 Florentina) is an S-type (stony) main belt asteroid with a diameter of 28 km.[2] It was discovered by Johann Palisa on 15 October 1891 in Vienna. He named the asteroid for his daughter, Florentine.[3]
Between 1874 and 1923, Palisa discovered a total of 122 asteroids.
This asteroid is a dynamic member of the
rotation period of 2.870±0.001 h. This is consistent with previous rotation estimates.[2]
A group of astronomers, including
Lucy d'Escoffier Crespo da Silva, contributed data toward the discovery of spin-vector alignments in the Koronis family, which includes (321) Florentina. This was based on observations made between 1998 through 2000. The collaborative work resulted in the creation of 61 new individual rotation lightcurves to augment previous published observations.[4]
