'''7P/Pons-Winnecke''' is a periodic [[comet]] in our [[solar system]].
[[Jean Louis Pons]] ([[Marseille]]) originally discovered the comet on [[June 12]], [[1819]], it was later rediscovered by [[Friedrich August Theodor Winnecke]] ([[Bonn]]) on [[March 9]], [[1858]]. It is believed to be the parent body of the [[June Bootids]] of late June. The nucleus has been estimated to be 2.6 km long.
7P has an orbital period of 6.37 years. It has a [[apsis|perihelion]] of 1.3 AU and an [[apsis| aphelion]] of 5.6 AU (past the orbit of Jupiter). It passed within 6 Gm (0.04 AU) of Earth in June 1927, and 16 Gm (0.1 AU) in 1939; but it will not come as close in the 21st century.
