752 Sulamitis

752 Sulamitis /suːləˈmaɪtɪs/ is an asteroid from the inner regions of the asteroid belt, approximately 60 kilometers (37 miles) in diameter. It is the parent body of the Sulamitis family (408),^[4] a small family of 300 known carbonaceous asteroids.^[8]: 23 This asteroid is orbiting 2.46 AU from the Sun with a period of 3.87 years and an eccentricity of 0.0743. The orbital plane is inclined at an angle of 5.96° to the plane of the ecliptic.^[3]

Sulamitis was discovered on 30 April 1913 by Georgian–Russian astronomer Grigory Neujmin at the Simeiz Observatory on the Crimean peninsula, and given the provisional designation 1913 RL.^[1] It was named after the Shulamite, a beautiful woman mentioned in the book Solomon's Song of Songs of the Old Testament. The figure is possibly the Queen of Sheba in the Hebrew Bible.^[2]

Photometric observations of this asteroid collected during 2004–2005 show a rotation period of 27.367±0.005 h with a brightness variation of 0.20±0.03 magnitude.^[7] A hydration feature in the spectrum of 752 Sulamitis indicates the surface has undergone aqueous alteration. The same feature appears in most of its family members, suggesting the original body held water in some form.^[9]
