[4][7] It orbits the Sun in the outer main-belt at a distance of 2.8–3.1 AU once every 5 years and 2 months (1,890 days).
The photometric observations were made in the 1990s, giving a well-defined rotation period of 7.004 hours with a brightness variation of 0.6 magnitude (U=3).
[6] According to the surveys carried out by NASA's WISE satellite with its subsequent NEOWISE mission, the asteroid measures 9.6 kilometers in diameter and its surface has an albedo of 0.145,[4][5] while the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.14 and calculates a diameter of 10.2 kilometers with an absolute magnitude of 12.7.
[3] This minor planet was named after the indigenous warrior Galvarino, the heroic figure during the Arauco War, a long-running conflict between colonial Spaniards and the Mapuche people of the 16th century in what is now Chile.
He was condemned by the Spanish soldiers to have his hands cut off and then to be freed as a living lesson to other Indians.
