1655 Comas Solà, provisional designation 1929 WG, is an asteroid from the outer region of the asteroid belt, about 30 to 40 kilometers in diameter. It was discovered by Spanish astronomer of Catalan origin, Josep Comas i Solà at the Fabra Observatory in Barcelona on 28 November 1929.[11]
The asteroid shows as rare XFU-type and B-type spectrum in the Tholen and SMASS classification scheme, respectively.[1] It orbits the Sun at a distance of 2.1–3.4 AU once every 4 years and 8 months (1,692 days). It has a long rotation period of 20 hours[8][9][10] and a geometric albedo of 0.07, according to the surveys carried out by IRAS, Akari, WISE and NEOWISE.[4][5][6][7]
The asteroid was named in memory of its discoverer Josep Comas i Solà (1868–1937), first director of the discovering Fabra Observatory, Barcelona, capital of the Catalonia region in northeastern Spain. He was a prolific observer of minor planets and comets in the 1920s. It is one of the rare cases where a minor planet bears the name of its discoverer. Solà is also honored by the asteroid 1102 Pepita, named after his nickname, and by the 127-kilometer wide Martian crater Comas Sola.[2]
