1735 ITA, provisional designation 1948 RJ1, is a carbonaceous asteroid from the outer region of the asteroid belt, about 62 kilometers in diameter. It was discovered on 10 September 1948 by Soviet–Russian astronomer Pelageya Shajn at the Simeiz Observatory located on the Crimean peninsula.[8]
The C-type asteroid orbits the Sun at a distance of 2.7–3.5 AU once every 5 years 7 months (2,032 days). Its orbit shows an eccentricity of 0.13 and is tilted by 16 degrees to the plane of the ecliptic. It has a rotation period of 12.6 hours[7] and an albedo of about 0.06, according to observations by IRAS, Akari and WISE/NEOWISE.[4][5][6]
It was named in 1979 on the occasion of the 60th anniversary of the founding of the USSR Academy of Sciences' Institute for Theoretical Astronomy (ITA), in what was then Leningrad.[2]
