1332 Marconia, provisional designation 1934 AA, is a dark

rotation period of 19.2 hours.[4]

Orbit and classification

Marconia is the

semi-major axis of 3.06 AU). Its orbit has an eccentricity of 0.13 and an inclination of 2° with respect to the ecliptic.[3]

The asteroid was first observed in October 1905, as A905 UD at

Heidelberg Observatory, where the body's observation arc begins as A924 EH in March 1924, almost 10 years prior to its official discovery observation at Pino Torinese.[1]

Physical characteristics

Marconia has been characterized as an

spectral type for members of the Marconia family is that of a carbonaceous C-type and X-type.[14]

Rotation period and poles

In September 2012, a first rotational

U=3).[11]

A 2016-published lightcurve, using modeled photometric data from the Lowell Photometric Database, gave a concurring sidereal period of 19.2264 hours, as well as a spin axes of (37.0°, 31.0°) and (220.0°, 31.0°) in ecliptic coordinates (λ, β).[12] Conversely, another lightcurve inversion study by an international collaboration gave a longer spin rate of 32.1201 hours.[13]

Diameter and albedo

According to the surveys carried out by the Japanese

albedo between 0.04 and 0.063.[6][7][8][9][10]

The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0527 and a diameter of 43.90 kilometers based on an absolute magnitude of 10.6.[4]

Naming

This

H 121). The lunar crater Marconi was also named in his honor.[2]
