Marcy remains active in her astronomy club including being the editor of a monthly newsletter. The great circles for meteors of a shower have two common intersection points; the radiant above the horizon and the anti-radiant below. The geometric definition of a great circle is the intersection of the sphere and a plane that passes through the center of the sphere. A meteor that does not point back to the known radiant for a given shower is known as a sporadic and is not considered part of that shower. Shower meteors may appear a short time before the radiant has risen in observer's eastern sky.

The meteor shower is commonly named after the constellation in which this radiant is found, and occurs annually during a well-defined time period. the sun, can push the dust away from the comet's orbit. One way to do this is to calculate (See Figures 2 and 3. Each shower has a radiant, or a point in the sky where the meteors appear to originate. The Geminids are expected to peak between Dec. 13 and Dec. 14 this year. It spends most of its time in a lazy, elliptical orbit in the outer solar People close to the equator will have the best chance to see the Eta Aquarids. The result?

Halley's comet has a period of 76 years and at its furthest the dust trail. It was Giovanni Schiaparelli who realized in 1865 that this comet was the source of the Perseids. The Orionid meteor shower is a result of Halley's Comet. Likewise, when Earth is fording a meteor stream in space, bits of comet dust are all around us. The shower can be seen in both the Northern and Southern Hemispheres, although only during the middle of the night in the latter and at a reduced rate.

This is due to the fact that fireballs originate from larger particles of cometary material. For example, the "Geminids" appear to originate in the constellation Gemini. And occasionally, when Jupiter gets close to a stream of debris, its immense gravity perturbs the particles, nudging them slightly closer to Earth and thereby increasing the number of meteors visible in the night sky. While rates will reduce by around 50 percent each night, the shower is still active enough to provide a decent show. It does not store any personal data.
