22P/Kopff

22P/Kopff is a periodic comet with an orbital period of approximately 6.5 years. It was discovered on August 23, 1906, by August Kopff at the Königstuhl Observatory in Heidelberg, Germany.

Kopff is a member of the Jupiter family of comets, a group of comets whose orbits are significantly influenced by Jupiter's gravity. Its perihelion (closest approach to the Sun) lies within the orbit of Mars, while its aphelion (farthest distance from the Sun) extends beyond Jupiter's orbit.

The comet has been observed on numerous apparitions since its discovery, allowing astronomers to study its composition and behavior as it approaches and recedes from the Sun. Observations have shown that 22P/Kopff experiences outbursts of activity, where its brightness increases significantly due to the release of volatile materials from its nucleus. The nucleus itself is estimated to be several kilometers in diameter.

22P/Kopff is considered to be a relatively well-studied comet, contributing to our understanding of cometary composition, dynamics, and evolution within the solar system. Its frequent returns make it a valuable target for continued observations.
