330 Adalberta (prov. designation: Template:Mp) is a stony asteroid from the inner regions of the asteroid belt, approximately 9.5 kilometers in diameter. It is likely named for either Adalbert Merx or Adalbert Krüger. It was discovered by Max Wolf in 1910. In the 1980s, the asteroid's permanent designation was reassigned from the non-existent object Template:Mp.Template:Efn<ref name="springer" /><ref name="MPC-Adalberta" />

DiscoveryEdit

Adalberta was discovered on 2 February 1910, by German astronomer Max Wolf at Heidelberg Observatory in southern Germany.<ref name="MPC-Adalberta" />

Previously, on 18 March 1892, another body discovered by Max Wolf with the provisional designation Template:Mp was originally designated Template:Mp, but was subsequently lost and never recovered (also see Lost minor planet). In 1982, it was determined that Wolf erroneously measured two images of stars, not asteroids. As it was a false positive and the body never existed,Template:Efn the name Adalberta and number "330" was then reused for this asteroid, Template:Mp, which itself was observed again briefly in 1937, 1951, 1974, 1978 (twice) and 1980, receiving a new designation on each occasion,<ref name="jpldata"/> before it was recognised that all of these observations were of the same object. MPC citation was published on 6 June 1982 (Template:Small).<ref name="springer" /><ref name="MPC-Circulars-Archive" />

Orbit and classificationEdit

The S-type asteroid orbits the Sun in the inner main-belt at a distance of 1.8–3.1 AU once every 3 years and 11 months (1,416 days). Its orbit has an eccentricity of 0.25 and an inclination of 7° with respect to the ecliptic.<ref name="jpldata" /> AdalbertaTemplate:'s observation arc begins with its official discovery observation at Heidelberg in 1910.<ref name="MPC-Adalberta" />

NamingEdit

This minor planet was named in honor of the discoverer's father-in-law, Adalbert Merx (after whom another minor planet 808 Merxia is also named). However it is also possible that it was named for Adalbert Krüger (1832–1896), a German astronomer and editor of the Astronomische Nachrichten, which was one of the first international journals in the field of astronomy.<ref name="springer" /> The naming citation was first mentioned in The Names of the Minor Planets by Paul Herget in 1955 (Template:Small).<ref name="springer" />

Physical characteristicsEdit

Rotation periodEdit

In 2013, a rotational lightcurve of Adalberta was obtained from photometric observations at Los Algarrobos Observatory Template:Obscode in Uruguay. Light-curve analysis gave a well-defined rotation period of Template:Val hours with a brightness variation of 0.44 magnitude (Template:Small).<ref name="Alvarez-2014a" />

Diameter and albedoEdit

According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Adalberta measures 9.11 kilometers in diameter, and its surface has an albedo of 0.256,<ref name="Masiero-2012" /> while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 9.84 kilometers using an absolute magnitude of 12.4.<ref name="lcdb" />
