302 Clarissa
302 Clarissa is a typical main belt asteroid. The asteroid was discovered by the French astronomer Auguste Charlois on 14 November 1890 in Nice. The origin of the name is unknown. In 1991, 302 Clarissa was being considered as a possible fly-by target for the Cassini spacecraft, but was later removed from consideration.
This body is orbiting the Sun with a period of and an eccentricity of 0.11. The orbital plane is inclined by 3.4° to the plane of the ecliptic. There are no major planetary resonances near the orbit of 302 Clarissa. It has a retrograde spin with a rotation period of 14.4797 hours. Stellar occultation data provides a size estimate of, while IRAS data gives a diameter of. It is classified as a F-type asteroid and is probably composed of carbonaceous material.
302 Clarissa provides the eponym for a small collisional asteroid family of mostly C-type asteroids. This group consists of 179 bodies with orbits clustered around 302 Clarissa. The family has a small extend of semimajor axis values, suggesting this is a young group; its estimated age is Myr. 70–90% of the objects in this family have a retrograde spin, suggesting the parent body may have possessed a similar rotation. This family is one of five that are candidate sources for the near Earth asteroids 101955 Bennu and 162173 Ryugu.
