PSR 1829-10 is a pulsar located in the Scutum Constellation. This pulsar has been the target of interest because of a mistaken identification of a planet around it. Andrew G. Lyne of the University of Manchester and Bailes claimed in July 1991 to have found “A planet orbiting the neutron star PSR1829-10”, Nature, 352, 311, but later retracted that in Nature, 355, 213, “No planet orbiting PSR 1829-10”, in 1992. They had failed to correctly take into account the ellipticity of Earth's orbit, and had incorrectly concluded that a planet with an orbital period of half-a-year existed around the pulsar.
