It was discovered by American astronomer Joel Hastings Metcalf on 7 December 1912 from Winchester, Massachusetts.
This stony S-type asteroid was named after the Peruvian city of Arequipa, where Harvard's Boyden Observatory was located prior to 1927.
The orbital plane is inclined at an angle of 12.4° to the ecliptic.
However, during the 2015 apparition, photometric measurements of the asteroid were taken from close to the equatorial perspective.
The resulting light curve displayed a rotation period of 7.0259±0.0003 h.[2]
