2741 Valdivia (
Cerro El Roble Station northwest of Santiago de Chile.[13] The asteroid was named after Spanish conquistador Pedro de Valdivia.[2]
Orbit and classification
Valdivia is a non-
Uccle Observatory in February 1935, where the body's observation arc begins just a two weeks later, or more than 40 years before its official discovery observation at Cerro El Roble.[13]

Physical characteristics
Rotation period
In August 2016, the so-far best-rated rotational

Poles
In 2016, an international study modeled a lightcurve with a concurring period of 4.09668±0.00005 hours and found two

Diameter and albedo
According to the survey carried out by the
albedo between 0.205 and 0.404,[4][6][7] while the Japanese Akari satellite found an albedo of 0.244 and a diameter of 10.73 kilometers.[5] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.10 – a compromise value between the carbonaceous (0.057) and stony (0.20) asteroids – and calculates a diameter of 17.52 kilometers based on an absolute magnitude of 11.9.[3]
