Comet 30P/Reinmuth, also known as Comet Reinmuth 1, is a periodic comet in the Solar System. It was first discovered by Karl 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 as Comet Taylor, which had been lost since 1915. Further calculations by George 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 to Jupiter, which increased the perihelion distance and orbital period.

Due to miscalculations, the 1942 appearance was missed, but it has been observed on every subsequent appearance since.

The comet nucleus is estimated to be 7.8 kilometers in diameter.[4]
