(11436) 1969 QR

It was discovered on 22 August 1969, by Czech astronomer Luboš Kohoutek at Bergedorf Observatory in Hamburg, Germany.

It orbits the Sun at a distance of 1.9–2.5 AU once every 3 years and 4 months (1,212 days).

[5] A rotational lightcurve for this asteroid was published by several Hungarian astronomers in August 2005.

The photometric observations gave a rotation period of 2.65 hours with a brightness variation of 0.27 magnitude (U=2).

[3] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 Flora, the largest member and namesake of its orbital family – and calculates a diameter of 3.7 kilometers.
