43P/Wolf–Harrington is a Jupiter-family comet discovered on December 22, 1924, by Max Wolf from the Heidelberg Observatory. In 2019, it passed within of Jupiter, which lifted the perihelion point and increased the orbital period to 9 years. The comet last came to perihelion in August 2025 and will return to perihelion in August 2034.
