It was discovered on 6 November 1931, by Soviet astronomer Grigory Neujmin at the Simeiz Observatory on the Crimean peninsula.
[4] In October 2005, a first rotational lightcurve of Patria was obtained from photometric observations by French amateur astronomer Laurent Bernasconi.
Lightcurve analysis gave a slightly longer-than average rotation period of 29.5 hours with a brightness amplitude of 0.12 magnitude (U=2).
[12] According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Patria measures between 30.72 and 34.98 kilometers in diameter and its surface has an albedo between 0.03 and 0.0462.
[6][7][8][9][10][11] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0506 and a diameter of 32.48 kilometers based on an absolute magnitude of 11.3.
