345 Tercidina is a large main-belt asteroid. It is classified as a C-type asteroid and is probably composed of carbonaceous material.
It was discovered by Auguste Charlois on November 23, 1892, in Nice.
Size
Observations of an occultation of a bright 5.5 magnitude star on September 17, 2002, produced seventy-five chords indicating an ellipsoid of 111×90 km.
Observations of an occultation on November 15, 2005, near Grass Valley, CA, produced five chords indicating an incomplete outline of 126×111 km. This larger result may be caused by a different orientation of the asteroid as it passed in front of the star.
