'''1735 ITA''' ([''prov. designation''](/source/Minor_planet_provisional_designation): {{mp|1948 RJ|1}}) is a carbonaceous [asteroid](/source/asteroid) from the outer region of the [asteroid belt](/source/asteroid_belt), approximately 62 kilometers in diameter. It was discovered on 10 September 1948, by Soviet–Russian astronomer [Pelageya Shajn](/source/Pelageya_Shajn) at the [Simeiz Observatory](/source/Simeiz_Observatory) located on the Crimean peninsula.<ref name="MPC-ITA" /> It was named for the [Institute for Theoretical Astronomy](/source/Institute_for_Theoretical_Astronomy) (ITA) in what is now [Saint Petersburg](/source/Saint_Petersburg), Russia.<ref name="springer" />

== Classification and orbit ==

''ITA'' orbits the Sun in the [outer](/source/Kirkwood_gap) main-belt at a distance of 2.7–3.5&nbsp;[AU](/source/Astronomical_unit) once every 5 years and 7 months (2,030 days). Its orbit has an [eccentricity](/source/orbital_eccentricity) of 0.13 and an [inclination](/source/orbital_inclination) of 16[°](/source/Degree_(angle)) with respect to the [ecliptic](/source/ecliptic).<ref name="jpldata" />

It was first identified as {{mp|A907 GC}} at [Heidelberg Observatory](/source/Heidelberg_Observatory) in 1907, extending the body's [observation arc](/source/observation_arc) by 41 years prior to its official discovery observation.<ref name="MPC-ITA" />

== Physical characteristics ==

ITA has been characterized as a carbonaceous [C-type asteroid](/source/C-type_asteroid).<ref name="lcdb" />

=== Lightcurves ===

In November 2004, a rotational [lightcurve](/source/lightcurve) was obtained by French amateur astronomer [René Roy](/source/Ren%C3%A9_Roy_(astronomer)), gave a [rotation period](/source/rotation_period) of 12.599 hours with a brightness variation of 0.27 [magnitude](/source/Magnitude_(astronomy)) ({{small|[U=3-](/source/LCDB_quality_code)}}).<ref name="geneva-obs" /> In March 2007, astronomers Laurent Brunetto and Jean-Gabriel Bosch derived a concurring period of 12.6 hours with and amplitude of 0.40 magnitude ({{small|[U=2-](/source/LCDB_quality_code)}})<ref name="geneva-obs" /> A 2016-published light-curve from the Lowell Photometric Database gave a period of 12.6103 hours ({{small|[U=n.a.](/source/LCDB_quality_code)}}).<ref name="Hanus-2016a" />

=== Diameter and albedo ===

According to the surveys carried out by the Infrared Astronomical Satellite [IRAS](/source/IRAS), the Japanese [Akari](/source/Akari_(satellite)) satellite, and NASA's [Wide-field Infrared Survey Explorer](/source/Wide-field_Infrared_Survey_Explorer) with its subsequent [NEOWISE](/source/NEOWISE) mission, ''ITA'' measures between 61.87 and 66.09 kilometers in diameter, and its surface has an [albedo](/source/astronomical_albedo) between 0.051 and 0.079.<ref name="Masiero-2012" /><ref name="SIMPS" /><ref name="AKARI" /> The ''Collaborative Asteroid Lightcurve Link'' derives an albedo of 0.0461 and a diameter of 61.93 kilometers with an [absolute magnitude](/source/absolute_magnitude) of 10.0.<ref name="lcdb" />

Between 2009 and 2023, 1735 ITA has been observed to [occult](/source/occultation) four stars.

== Naming ==

This [minor planet](/source/minor_planet) was named in 1979, on the occasion of the 60th anniversary of the founding of the [USSR Academy of Sciences](/source/USSR_Academy_of_Sciences){{'}} Institute for Theoretical Astronomy (ITA), in what was then [Leningrad](/source/Leningrad%2C_Russia).<ref name="springer" /> The official naming citation was published by the [Minor Planet Center](/source/Minor_Planet_Center) on 1 June 1980 ({{small|[M.P.C.](/source/Minor_Planet_Circulars) 5357}}).<ref name="MPC-Circulars-Archive" />
