4332 Milton, provisional designation Template:Mp, is a background asteroid from the central regions of the asteroid belt, approximately Script error: No such module "convert". in diameter. It was discovered on 5 September 1983, by American astronomer Carolyn Shoemaker at the Palomar Observatory in California.[1] The X e-subtype has a rotation period of 3.3 hours.[2] It was named after Daniel Milton, American geologist with the USGS.[1]
Orbit and classification
Milton is a non-family asteroid from the main belt's background population.[3] It orbits the Sun in the central asteroid belt at a distance of 1.8–3.4 AU once every 4 years and 2 months (1,518 days; semi-major axis of 2.58 AU). Its orbit has an eccentricity of 0.32 and an inclination of 19° with respect to the ecliptic.[4]
The asteroid was first observed as Template:Mp at Heidelberg Observatory in September 1933. The body's observation arc begins with its official discovery observation at Palomar in September 1983.[1]
Physical characteristics
In the SMASS classification, Milton is a Xe-subtype that transitions between the X-type and E-type asteroids.[4] It has also been characterized as a carbonaceous C-type by Pan-STARRSTemplate:' large-scale survey.[5]
Rotation period
In September 2008, a rotational lightcurve of Milton was obtained from photometric observations by Julian Oey at the Kingsgrove Template:Obscode and Leura Template:Obscode observatories. Lightcurve analysis gave a rotation period of 3.2978 hours with a brightness variation of 0.30 magnitude (U=2+Script error: No such module "Check for unknown parameters".).[6] In August 2012, a refined period of 3.295 hours and an amplitude of 0.16 magnitude was measured by Afşar Kabaş at the Çanakkale University Observatory in Turkey (U=3-Script error: No such module "Check for unknown parameters".).[7]
Diameter and albedo
According to the surveys carried out by the Infrared Astronomical Satellite IRAS and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Milton measures between 11.500 and 11.54 kilometers in diameter and its surface has an albedo between 0.1002 and 0.2306.[8][9]
The Collaborative Asteroid Lightcurve Link derives an albedo of 0.1158 and a diameter of 11.26 kilometers based on an absolute magnitude of 12.7.[2]
Only one brief stellar occultation by 4332 Milton has been observed to date, in 2021.
Naming
This minor planet was named after Daniel J. Milton (1934-2024), American geologist with the United States Geological Survey, known for his geological studies of the Moon and Mars, as well as for research on impact craters and features in Australia.[1] The official naming citation was published by the Minor Planet Center on 30 January 1991 (M.P.C. 17656Script error: No such module "Check for unknown parameters".).[10]
