1119 Euboea (; prov. designation 1927 UB ) is a background asteroid from the central region of the asteroid belt . It was discovered on 27 October 1927, by German astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory in southwest Germany.[3] rotation period of 11.4 hours and measures approximately 30 kilometers (19 miles) in diameter. It was named for the Greek island of Euboea .[2]
Orbit and classification [ edit ]
Euboea is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements .[4] [5] central asteroid belt at a distance of 2.2–3.0 AU semi-major axis of 2.61 AU ). Its orbit has an eccentricity of 0.16 and an inclination of 8° with respect to the ecliptic .[1] observation arc begins with a recovered observation from the Lowell Observatory in April 1930, more than 2 years after to its official discovery observation.[3]
This minor planet was named after Euboea , also known as "Negropont", the largest island of Greece in the Aegean Sea . The naming was mentioned in The Names of the Minor Planets by Paul Herget in 1955 (H 105 [2]
Physical characteristics [ edit ]
Euboea is an assumed stony S-type asteroid .[9]
Rotation period and poles [ edit ]
In October 2007, a first rotational lightcurve of Euboea was obtained from photometric observations by astronomers at the Oakley Southern Sky Observatory in Australia. Lightcurve analysis gave a rotation period of 11.41 hours with a brightness variation of 0.50 magnitude (U=3 [15] Pierre Antonini (U=3 [12]
In 2016, two modeled lightcurves were published using photometric data from the Lowell Photometric Database and other sources. They gave a concurring sidereal period of 11.3981 and 11.39823 hours, respectively.[13] [14] spin axes of (79.0°, 75.0°) and (282.0°, 55.0°),[13] [14] in ecliptic coordinates (λ, β).
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 , Euboea measures between 18.37 and 31.90 kilometers in diameter and its surface has an albedo between 0.0576 and 0.213.[6] [7] [8] [10] [11] Collaborative Asteroid Lightcurve Link derives a low albedo of 0.0539 – typical for carbonaceous C-type asteroids – and a diameter of 31.46 kilometers based on an absolute magnitude of 11.3.[9]
