735 Marghanna (

rotation period of 20.6 hours and is rather regular in shape. It was named after Margarete Vogt and after Hanna, the mother and a relative of the discoverer, respectively.[2]

Orbit and classification

Marghanna is a non-

Heidelberg Observatory on 29 November 1921, almost nine years after its official discovery observation.[1]

Physical characteristics

In the

SMASS classification, it is a hydrated C-type (Ch).[3][5][12]

Diameter and albedo

According to the surveys carried out by the

albedo of (0.059±0.007), (0.0484±0.0484) and (0.043±0.002), respectively.[7][8][9]

The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0423 and a diameter of 74.23 kilometers based on an absolute magnitude of 9.7,[15] while the Cornell Mid-IR Asteroid Spectroscopy (MIDAS) survey determined a diameter of (73±6) kilometers and Benoit Carry one of (72.27±2.22) kilometers.[10][16] Alternative mean-diameters published by the WISE team include (57.25±26.07 km), (67.976±0.404 km), (70.640±1.230 km) and (87.951±34.60 km) with a corresponding albedo of (0.05±0.09), (0.059±0.007), (0.0536±0.0078) and (0.0275±0.0259).[5][15]

Two

asteroid occultations on 11 March 2008 and on 4 May 2010, gave a best-fit ellipse dimension of (81.6 km × 73.5 km) and (74.0 km × 64.0 km), respectively, each with an intermediate quality rating of 2.[5] These timed observations are taken when the asteroid passes in front of a distant star.[5]
