103 Hera is a moderately large main-belt asteroid with an orbital period of Script error: No such module "convert".. It was discovered by Canadian-American astronomer James Craig Watson on September 7, 1868,[1] and named after Hera, queen and fifth in power of the Olympian gods in Greek mythology. This is a stony S-type asteroid[2] with a silicate surface composition.
Photometric observations made in 2010 at the Organ Mesa Observatory at Las Cruces, New Mexico, and the Hunters Hill Observatory at Ngunnawal, Australian Capital Territory, give a synodic rotation period of Script error: No such module "val".. The bimodal light curve shows a maximum brightness variation of 0.45 ± 0.03 in magnitude.[3]
Measurements made with the IRAS observatory give a diameter of Script error: No such module "val". and a geometric albedo of Script error: No such module "val".. By comparison, the MIPS photometer on the Spitzer Space Telescope gives a diameter of Script error: No such module "val". and a geometric albedo of Script error: No such module "val".. When the asteroid was observed occulting a star, the chords showed a diameter of Script error: No such module "val"..[4]
