45P/Honda–Mrkos–Pajdušáková is a short-period comet discovered by Minoru Honda December 3, 1948.[5] The comet is named after Minoru Honda, Antonín Mrkos, and Ľudmila Pajdušáková. The comet is on an elliptical orbit with a period of 5.26 years.[1] The comet nucleus is estimated to be 0.5-1.6 kilometers in diameter.[1][6] During the 2011 perihelion passage the comet was recovered on 5 June 2011 at apparent magnitude 21.[7] On 8 July 2011 the comet had a magnitude of approximately 18,[8] and as of 22 July 2011 the comet's nuclear condensation had a magnitude of approximately 16.[9] The comet is expected to reach a peak magnitude of around 7.3 in late September when it is near perihelion.[10]

The comet made a close approach of only 0.0600 AU (8,980,000 km; 5,580,000 mi) from the Earth on August 15, 2011,[11][12] and was studied by the Goldstone Deep Space Network on August 19 and 20.[6] Goldstone radar observations on 2011 August 19 and 20 detected echoes from the nucleus and coma.[13] This is only the fifteenth comet that has been detected with radar.[13] The comet will also pass close to Earth on February 11, 2017.[11]

During the 1995 perihelion passage the comet was visible to Solar and Heliospheric Observatory (SOHO) on January 16, 1996 when the comet was around apparent magnitude 7 and 4.3° from the Sun.[5]
