1018 Arnolda, provisional designation Template:Mp, is a stony asteroid from the central regions of the asteroid belt, approximately 16 kilometers in diameter. It was discovered on 3 March 1924, by German astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory in southwest Germany.[1] The asteroid was named after physicist Arnold Berliner.[2]
Classification and orbit
Arnolda is not a member of any known asteroid family. It orbits the Sun in the central main belt at a distance of 1.9–3.2 AU once every 4 years and 1 month (1,480 days). Its orbit has an eccentricity of 0.25 and an inclination of 8° with respect to the ecliptic.[3] The body's observation arc begins nine days prior to its official discovery observation at Heidelberg.[1]
Physical characteristics
Arnolda is an assumed stony S-type asteroid, a very common type in the inner and in parts of the central asteroid belt.[4]
Lightcurves
In May 2005, the best-rated rotational lightcurve of Arnolda was obtained from photometric observations by Australian astronomers at the Oakley Southern Sky Observatory (E09Script error: No such module "Check for unknown parameters".). Lightcurve analysis gave a rotation period of 14.617 hours with a brightness variation of 0.33 magnitude (U=3Script error: No such module "Check for unknown parameters".).[5] Several other astronomers obtained number of lesser-rated lightcurves with a shorter period (U=n.a./1/2/3-Script error: No such module "Check for unknown parameters".).[6][7]Template:Efn
Diameter and albedo
According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Arnolda measures between 13.68 and 16.557 kilometers in diameter and its surface has an albedo between 0.29 and 0.439.[8][9][10][11][12]
The Collaborative Asteroid Lightcurve Link derives a high albedo of 0.3760 and a diameter of 16.44 kilometers based on an absolute magnitude of 10.60.[4]
Naming
This minor planet was named after physicist Arnold Berliner (1862–1942), on the occasion of his 70th birthday in 1933. Berliner was the editor of the prominent German periodical scientific magazine Naturwissenschaften (AN 247Script error: No such module "Check for unknown parameters".).[2]
