The Discovery of the Pi Puppid Meteor Shower

The Pi Puppids were discovered in 1972, radiating from the constellation Puppis.

 

 

 

The Parent Body of the Pi Puppid Meteor Shower

The Pi Puppid Meteor Shower is the dust and debris left behind by Comet Grigg-Skjellerup (26P/Grigg-Skjellerup). It is a Jupiter Family Comet that orbits the Sun once every 5.31 years. This comet's orbital path has been wildly affected by the gravity of Jupiter. The Jet Propulsion Laboratory estimates that 26P/Grigg-Skjellerup is 2.6-kilometers-wide.

 

Comet Grigg-Skjellerup was visited by the European Space Agency's Giotto probe in July of 1992. Unfortunately, it could not take images of the comet during its close fly-by since the camera was damaged six years earlier, in 1986, when it came within 596 kilometers of Halley's Comet.
