Geraldina (minor planet designation: 300 Geraldina) is a large Main belt asteroid.[1] It was discovered by Auguste Charlois on October 3, 1890, in Nice. The origin of the name is unknown.[2] It is orbiting the Sun at a distance of 3.21 astronomical unit|AU with a period of 5.74 yr and an eccentricity (ovalness) of 0.057. The orbital plane is tilted at an angle of 0.73° to the plane of the ecliptic.[1]
Light curve analysis based on photometric observations of this asteroid made during 2005 show a rotation period of 6.842±0.001 h with a brightness variation of 0.18 in magnitude.[3]
