PSR B1829−10

PSR B1829−10 (often shortened to PSR 1829−10) is a pulsar that is approximately 30,000 light-years away in the constellation of Scutum. 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 PSR 1829-10"^[1] but in 1992 retracted.^[2] 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.
