1834 Palach, provisional designation 1969 QP, is a stony asteroid from the outer region of the asteroid belt. It was discovered on 22 August 1969 by Czech astronomer Luboš Kohoutek at Bergedorf Observatory in Hamburg, Germany.[8]
The asteroid measures about 19 kilometers in diameter and orbits the Sun at a distance of 2.8–3.2 AU once every 5 years and 3 months (1,921 days). It has a rotation period of 3.14 hours. The geometric albedo of the S-type asteroid is about 0.11–0.14.[3][4][5]
It was named in memory of Czech student Jan Palach, who burned himself to death, as a protest against the Soviet occupation of Czechoslovakia that followed and ended the national reform movement known as the Prague Spring.[2]
