793 Arizona is aminor planet orbiting theSun that was discovered April 9, 1907 by American businessmanPercival Lowell atFlagstaff.[3] It was named for the state ofArizona.[4] The object was independently discovered on April 17, 1907, byJ. H. Metcalf atTaunton.[3] This is amain belt asteroid orbiting2.8 AU from the Sun with aperiod of 4.675 yr and aneccentricity (ovalness) of 0.13. Theorbital plane is inclined at an angle of 15.8° to theplane of the ecliptic.[1]
Photometric observations at the Palmer Divide Observatory inColorado Springs, Colorado during the winter of 2007–2008 were used to build alight curve for this asteroid. The asteroid displayed a period of7.367±0.005 h and a brightness change of0.25±0.02 inmagnitude.[2] It spans a diameter of approximately 29 km and is a candidateD-type asteroid with an unusual spectrum.[1]
