Comet30P/Reinmuth, also known asComet Reinmuth 1, is aperiodic comet in theSolar System. It was first discovered byKarl Reinmuth (Landessternwarte Heidelberg-Königstuhl, Germany) on February 22, 1928.
Initial calculations of its orbit estimated a period of 25 years, but this was later revised to seven years, leading to speculation that it was the same comet asComet Taylor, which had been lost since 1915. Further calculations byGeorge van Biesbroeck concluded that they were different comets.
The 1935 approach was observed, though it was not as favorable. In 1937, the comet passed close toJupiter, which increased theperihelion distance andorbital period.
Due to miscalculations, the 1942 appearance was missed, but it has been observed on every subsequent appearance since.
Thecomet nucleus is estimated to be 7.8 kilometers in diameter.[5]
