7P/Pons–Winnecke is a periodic comet of the Jupiter family with an orbital period of 6.37 years. It was discovered in June 1819 by Jean-Louis Pons, and rediscovered by Friedrich August Theodor Winnecke in March 1858. The comet is the parent body of the Bootid meteor shower. Early calculations of the 1921 appearance showed the possibility of the comet colliding with Earth, but later calculations ruled out this possibility. Despite this, the comet passed close to Earth in June 1927 at a distance of 6 million kilometers (0.04 AU).
