1992 Galvarino, provisional designation 1968 OD, is an Eoan asteroid from the outer region of the asteroid belt, approximately 10 kilometers in diameter.
It was discovered on 18 July 1968, by Chilean astronomers Carlos Torres and S. Cofre at the Cerro El Roble Station of Chile's National Astronomical Observatory, and named after the indigenous warrior Galvarino.
Galvarino is a stony S-type asteroid and a member of the Eos family, an orbital group of more than 4,000 asteroids, which are well known for mostly being of stony composition with a relatively high albedo. It is also classified as a M- and L-type asteroids by WISE and PanSTARRS, respectively.
It orbits the Sun at a distance of 2.8–3.1 AU once every 5 years and 2 months (1,891 days). Its orbit has an eccentricity of 0.05 and an inclination of 11° with respect to the ecliptic. Its observation arc begins with its official discovery observation in 1968, as no precoveries and no previous identifications were made.
As of 2016, a single rotational lightcurve of Galvarino has been obtained. 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).
