782 Montefiore is a minor planet, specifically an asteroid orbiting in the asteroid belt that was discovered by Austrian astronomer Johann Palisa on 18 March 1914 and named for Clarice Sebag-Montefiore, wife of Alfons von Rothschild of Vienna. It is orbiting 2.18 astronomical unit|AU from the Sun with an eccentricity of 0.04 and a period of 3.22 yr. The orbital plane of this asteroid is inclined by an angle of 5.26° to the plane of the ecliptic.
10μ radiometric data collected from Kitt Peak in 1975 gave a diameter estimate of 15 km.[2] Photometric light curve studies from 1997 onward give a consistent rotation period of 4.07 hours.[3]
