266 Aline is a fairly large main belt asteroid that was discovered by Johann Palisa on May 17, 1887 in Vienna and is thought to have been named after the daughter of astronomer Edmund Weiss. It is a dark C-type asteroid and is probably composed of primitive carbonaceous material.
Photometric observations made in 2012 at the Organ Mesa Observatory in Las Cruces, New Mexico produced a light curve with a period of 13.018 ± 0.001 hours and a brightness variation of 0.10 ± 0.01 in magnitude.[2]
