1708 Polit, provisional designation 1929 XA, is a dark and eccentric asteroid from the outer region of the asteroid belt, about 29 kilometers in diameter. It was discovered by Spanish astronomer of Catalan origin Josep Comas i Solà at the Fabra Observatory in Barcelona on 30 November 1929.[10]
The C-type asteroid orbits the Sun at a distance of 2.0–3.8 AU once every 4.97 years (1,817 days). Its orbit shows a high eccentricity of 0.31 and is inclined by 6 degrees to the plane of the ecliptic. Light-curve observations gave a rotation period of 7.520 hours. The carbonaceous asteroid has a low geometric albedo of about 0.04.[4][5][6]
The asteroid was named in memory of the Fabra Observatory's second director of the astronomical section, Isidre Pólit (1880–1958), who was an assiduous observer of minor planets and comets.[2]
