1248 Jugurtha (prov. designation 1932 RO ) is a stony background asteroid from the central regions of the asteroid belt , approximately 29 kilometers (18 miles) in diameter. Discovered by Cyril Jackson at the Union Observatory in 1932, the asteroid was named after Jugurtha , the ancient North African king of Numidia . The S-type asteroid is likely elongated in shape and has a rotation period of 12.9 hours.[14]
Discovery
[ edit ]
Jugurtha was discovered on 1 September 1932, by South African astronomer Cyril Jackson at the Union Observatory in Johannesburg.[1] Grigory Neujmin at the Simeiz Observatory on the Crimean peninsula.[3] Minor Planet Center only recognizes the first discoverer.[1]
Orbit and classification
[ edit ]
Jugurtha is a non-family asteroid from the main belt's background population .[6] [5] central asteroid belt at a distance of 2.7–2.8 AU semi-major axis of 2.72 AU ). Its orbit has an eccentricity of 0.02 and an inclination of 9° with respect to the ecliptic .[4] observation arc begins with its first observation as A901 VE at Heidelberg Observatory in November 1901, nearly 31 years prior to its official discovery, .[1]
Naming
[ edit ]
This minor planet was named after Jugurtha (160–104 BC), a king of Numidia in North Africa, opposed to and defeated by Rome in the Jugurthine War (112–106 BC). The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 (H 115 [3]
Physical characteristics
[ edit ]
In the SMASS classification , Jugurtha is a common, stony S-type asteroid .[6] [14]
Rotation period
[ edit ]
Several rotational lightcurves of Jugurtha have been obtained from photometric observations since 2001.[14] [13] [15] [a] rotation period of ± 0.002magnitude (U=3 [12] spin axis of (254.0°, −89.0°) in ecliptic coordinates (λ, β).[16]
Diameter and albedo
[ edit ]
According to the surveys carried out by the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer , Jugurtha measures between 27.46 and 33.559 kilometers in diameter and its surface has an albedo between 0.2073 and 0.282.[7] [8] [9] [10] [11] Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 31.12 kilometers based on an absolute magnitude of 9.9.[14]
