43P/Wolf–Harrington is a periodic comet discovered on December 22, 1924, by Max Wolf in Heidelberg, Germany. In 2019 it passed within 0.065 AU (9,700,000 km; 6,000,000 mi) of Jupiter, which lifted the perihelion point and increased the orbital period to 9 years. During the 1997 apparition the comet reached an apparent magnitude a little bit brighter than 12. The comet nucleus is estimated to be 3.6 kilometers in diameter.
