1215 Boyer, provisional designation 1932 BA, is a stony Eunomian asteroid from the central region of the asteroid belt, approximately 20 kilometers in diameter. It was discovered by astronomer Alfred Schmitt in 1932, who named it after French astronomer and college Louis Boyer.[11]

Discovery

Boyer was discovered on 19 January 1932, by French astronomer

Heidelberg Observatory in Germany.[2] The body's observation arc begins at Algiers with its official discovery observation.[11]

Diameter and albedo

According to the surveys carried out by the Japanese

albedo between 0.116 and 0.3012.[5][6][7][8][9]

The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.21, derived from the Eunomia family's largest member and namesake, 15 Eunomia, and calculates a diameter of 17.47 kilometers with an absolute magnitude of 11.1.[3]
