Meteor showers and comets

Meteor shower that occurred during the span of one calendar year can not be separated by the presence of a comet. Let us see the meteor shower calendar.

When comets (including Tempel-Tuttle) passes close to the Sun, comet become smaller 
because the surface melts and sheds more dust and debris.

Draconid meteor shower (early October) is caused by the comet Giacobini-Zinner. Draconid a meteor shower meteor shower because the nature of comets that periodically affect this meteor shower is still solid but the dust is concentrated around this comet.

Comet Tempel-Tuttle, the Leonid meteor shower causes the presence of which occurred in mid-November. Paste the nature of dust-Tuttle comet remnants of this dust is scattered along the path is thin but high density around the core kometnya.

Halley's Comet into the cause of the presence of Eta Aquarid meteor shower (early May) and Orionid that occurred in mid-October. While the Perseid meteor shower that occurred in mid-August came from the dust of comet Swift-Tuttle.

Some meteor showers like Andromedid (mid November) is caused by a comet that has broken from Biela's comet dust that collapse around the year 1860. Geminid meteor shower that occurred mid-December due to the death comet that now only a core course that is the asteroid Phaethon.

The presence of a periodic comet that causes the presence of meteor showers can also be unpredictable and the experts are able to make a meteor shower calendar as a guide to enjoying the most amazing natural phenomena.
