(1834) Palach is an asteroid of the outer main belt , which was discovered on August 22, 1969 by the Czech astronomer Luboš Kohoutek at the Hamburg-Bergedorf observatory ( IAU code 029) in Hamburg .
The asteroid belongs to the Eos family, a group of asteroids, which typically have large semiaxes from 2.95 to 3.1 AU , bounded inward by the Kirkwood gap of the 7: 3 resonance with Jupiter , and orbital inclinations between 8 ° and 12 °. The group is named after the asteroid (221) Eos . The family is believed to have emerged from a collision more than a billion years ago.
(1834) Palach is named after the Czech student Jan Palach (1948–1969) who burned himself to death on January 16, 1969 on Wenceslas Square in Prague in protest against the occupation of Czechoslovakia .
