1826 Miller, provisional designation 1955 RC1, is a stony asteroid from the outer region of the asteroid belt, about 24 kilometers in diameter. It was discovered on September 14, 1955 by the Indiana Asteroid Program at Goethe Link Observatory near Brooklyn in the U.S. state of Indiana.[9] Prior to its official discovery date the asteroid had been observed since the late 1920s and received numerous provisional designations, such as 1929 RV, 1940 WF and 1950 TD2.
The asteroid orbits the Sun at a distance of 2.7–3.2 AU once every 5 years and 2 months (1,893 days). It is a relatively slow rotator with a rotation period of 30 hours.[7] Previously, measurement of its light-curve gave a much shorter period of 6.77 h.[8] The S-type asteroid has an albedo of 0.129[4] with other observations and derived figures in the range of 0.11 to 0.20.[3][5][6]
The asteroid was involved in the occultation of a 10th magnitude star in the constellation Cancer in April 2004.[10]
It was named in honor of American entrepreneur John A. Miller (1872–1941), founder of the Astronomy Department at Indiana University and first director of the Kirkwood Observatory, which he built and named for his former teacher. He also built the Sproul Observatory at Swarthmore College in the U.S state of Pennsylvania (also see 1578 Kirkwood).[2]
