Discovery and study of Comet 67P/Churyumov−Gerasimenko, the main target of the Rosetta space mission
Rosetta, a European space vehicle, which was 15 years in development, headed for short-period Comet 67P/Churyumov–Gerasimenko in February 2004. In September 1969 S. Gerasimenko and the author went to the Alma-Ata Astrophysical Institute to carry out a survey of short-period and new comets. At a late...

At a later date of that month, the author examined the exposure of Comet 32P/Comas Sola made on September 11.92 UT, 1969 and found a cometary object near the plate centre. The author assumed it to be the expected short-period Comet 32P/Comas Sola. Later explorations at the Kyiv University revealed that this comet’s position differed from predicted calculations for Comet 32P by 1.8°. It was a new comet.
