737 Arequipa is a minor planet orbiting the Sun. 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. It is orbiting at a distance of 2.59 AU from the Sun, with an orbital eccentricity (ovalness) of 0.245 and a period of 4.17 yr. The orbital plane is inclined at an angle of 12.4° to the ecliptic.[1]
The rotation period of this asteroid has proven to be a challenge to determine, most likely because it has a complex shape and a
rotation axis with a low inclination. 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]
