It was discovered on 23 March 1933, by Belgian astronomer Sylvain Arend at Uccle Observatory in Belgium. It is named for the city of Warsaw. Orbit and classification Varsavia orbits the Sun in the central main-belt at a distance of 2.2–3.2 AU once every 4 years and 4 months (1,589 days). Its orbit has an eccentricity of 0.19 and an inclination of 29° with respect to the ecliptic. As no precoveries were taken, and no prior identifications were made, the body's observation arc begins with its official discovery observation at Uccle in 1933. Physical characteristics Varsavia is an X-type asteroid in the Tholen taxonomy. In the SMASS classification, it is a Xc-type, that transitions to the carbonaceous C-type asteroids. Rotation period In April 2003, the first rotational lightcurve of Varsavia was obtained by American astronomer Brian Warner at his Palmer Divide Station in Colorado. Revised data gave a well-defined rotation period of 7.1639 hours with a brightness variation of 0.15 magnitude (U=3).lightcurve-plot Another well defined period of 7.1680 hours (Δ0.15 mag) was derived from photometric observations taken by Australian astronomer Julian Oey at Leura Observatory in February 2011 (U=3).LCDB-Oey-2011 Concurring results were also obtained by Robert Stephens in April 2003 (7.231 h; Δ0.15 mag; U2), from the Palomar Transient Factory in June 2012 (7.1659 h; Δ0.28 mag; U2), and by the "Spanish Photometric Asteroid Analysis Group" (OBAS) in May 2016 (7.163 h; Δ0.12 mag; U=3-). Observations made with the TESS space telescope in 2018 gave a period of 7.1615 hours with an amplitude of 0.05 magnitude (U=2).Solar System Objects Observed with TESS—First Data Release: Bright Main-belt and Trojan Asteroids from the Southern Survey Pál, András Szakáts, Róbert Kiss, Csaba Bódi, Attila Bognár, Zsófia Kalup, Csilla Kiss, László L.

The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0874 and adopts a diameter of 41 kilometers, obtained from modeled data and a directly observed minor planet occultation of a star. On July 18, 2003, a stellar occultation by 1263 Varsavia was observed at multiple sites. The measured chords yielded an equivalent diameter of 41 8 km. The profile best matched a spin vector of (λp, βp) = (341°, −14°) in elliptical coordinates. Naming This minor planet was named by Tadeusz Banachiewicz after the Latin name of the city of Warsaw, capital of Poland. The naming citation includes a note of thanks for the support given by the city's observatory. Naming citation was first published in German by Astronomisches Rechen-Institut (RI 843).
