2026 Cottrell, provisional designation 1955 FF, is a dark asteroid from the inner regions of the asteroid belt, approximately 12 kilometers in diameter.

The asteroid was discovered on 30 March 1955, by

IU's Indiana Asteroid Program at Goethe Link Observatory near Brooklyn, Indiana, United States.[12] It was named after American chemist Frederick Gardner Cottrell.[2]

Orbit and classification

Cottrell orbits the Sun in the inner main-belt at a distance of 2.2–2.7 AU once every 3 years and 10 months (1,398 days). Its orbit has an eccentricity of 0.12 and an inclination of 2° with respect to the ecliptic.[1]

In March 1951, the asteroid was identified as 1951 EL1 at Nice Observatory and two days later at McDonald Observatory, extending the body's observation arc by four years prior to its official discovery observation at Goethe Link.[12]

Diameter and albedo

According to the surveys carried out by the Japanese

albedo between 0.050 and 0.088.[4][5][6][7][8]

The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and consequently calculates a much smaller diameter of 7.46 kilometers based on an absolute magnitude of 13.0.[3]
