It was discovered in 1959 by Charles D. Slaughter and Robert Burnham of the Lowell Observatory, Flagstaff, Arizona during a photographic survey. They spotted the comet, with a faint brightness of magnitude 16, on a plate exposed on 10 December 1958. By monitoring its movement over a series of consecutive days, Elizabeth Roemer was able to calculate its orbit, suggesting a perihelion date of 4 August 1958 and an orbital period of 11.18 years.
It was subsequently observed in 1970, 1981, 1993, 2005 and 2016. Its next perihelion will be on December 19, 2027.[5]
The nucleus of the comet has a radius of 1.55 kilometers based on observations by Keck.[6]
