760 Massinga (Adam Massinger (1888–1914), a German astronomer at Heidelberg who was killed in World War I.[2]
Orbit and classification
Massinga is a non-
semi-major axis of 3.15 AU). Its orbit has an eccentricity of 0.23 and an inclination of 13° with respect to the ecliptic.[3]
Discovery
Massinga was discovered by Franz Kaiser at the Heidelberg-Königstuhl State Observatory in southwest Germany on 28 August 1913. On the same night, it was independently discovered by Russian astronomer Grigory Neujmin at the Simeiz Observatory on the Crimean peninsula. The Minor Planet Center, however, only credits Franz Kaiser with the discovery. The body's observation arc begins at Heidelberg on 8 November 1914, more than a year after its official discovery observation.[1]
Naming

H 76).[2]
Physical characteristics
In the
Small Solar System Objects Spectroscopic Survey (S3OS2), it is an S-type and SL-type, latter which transitions to the uncommon L-type, respectively.[5][12]
Rotation period
In December 1999, a rotational
U=3-).[14]
Diameter and albedo
According to the surveys carried out by the
albedo of (0.2276±0.012), (0.237±0.011) and (0.360±0.322), respectively.[7][8][9] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.2392 and a diameter of 71.47 kilometers based on an absolute magnitude of 7.9.[15]
On 29 February 2012, an
asteroid occultation of Massinga gave a best-fit ellipse dimension of (80.2 km × 56.2 km), with a high quality rating of 3. These timed observations are taken when the asteroid passes in front of a distant star.[5]
