7P/Pons–Winnecke (also known as Comet Pons–Winnecke) is a periodic Jupiter-family comet with a 6-year orbit. Early calculations for the 1921 apparition suggested that the orbit of the comet might collide with Earth in June, but observations on April 10 ruled out an impact. It made a very close approach to Earth in June 1927. The outward migration of perihelion created impressive meteor showers in 1916, 1921, and 1927. The last perihelion was on January 30, 2015, and at the 2015 perihelion it had a solar elongation of 24 degrees. The comet nucleus is estimated at about 5.2 km in diameter.
