652 Jubilatrix

652 Jubilatrix is a minor planet, specifically an asteroid orbiting in the asteroid belt. It was discovered on 4 November 1907 by Austrian astronomer Johann Palisa, and was named in honor of the 60th anniversary of the reign of Franz Joseph.^[2] The asteroid is orbiting at a distance of 2.55 AU with a period of 4.08 yr and an eccentricity of 0.127.^[1] It is a member of the Maria dynamic family.^[3] Photometric observations provide a rotation period of 2.6627±0.0001 h with a brightness variation of 0.27±0.03 in magnitude.^[4]
