With about the same frequency that three large comets (2 long period and 1 short period) visit the inner solar system... Panstarrs visits once every 110,000 years. I hope the sun does not have a bad spell
The other thing that occurs approx once every 500 years as found in ice cores is: Ice cores <http://en.wikipedia.org/wiki/Ice_core> contain thin nitrate-rich layers that can be analyzed to reconstruct a history of past events before reliable observations; the data from Greenland ice cores was gathered by Kenneth G. McCracken <http://en.wikipedia.org/wiki/Kenneth_G._McCracken>[9]<http://en.wikipedia.org/wiki/Solar_storm_of_1859#cite_note-9> and others. These show evidence that events of this magnitude—as measured by *high-energy proton radiation*, not geomagnetic effect—occur approximately once per 500 years, with events at least one-fifth as large occurring several times per century.[10]<http://en.wikipedia.org/wiki/Solar_storm_of_1859#cite_note-mccracken-10> Less severe storms have occurred in 1921 and 1960, when widespread radio disruption was reported. If I am right about Comets and dark matter, through beta decay they should create a massive number of protons, electrons and neutrinos in their path, which as I said earlier is very bad for DNA as well as IPADS and Power Grids If you don’t see the comet this time around, you’ll have to wait 7 years for its return. Hergenrother is a *short* ***period* or *periodic* comet – one that orbits the sun in fewer than 200 years. That’s what the “P” stands for in its name. Since its discovery in 1998 by American astronomer Carl Hergenrother, this feathery visitor is making its third observed trip. About 265 numbered periodic comets have been discovered to date. Unnumbered periodic comets number nearly 250. Next in our comet lineup is comet *C/2011 L4 PANSTARRS*<http://cometography.com/lcomets/2011l4.html>. The “C” indicates a long-period comet or one that orbits the sun in more than 200 years. Two hundred? That’s nothing. L4 Pan-STARRS’s period is estimated at 110,000 years. Seeing it’s a once-in-a-lifetime experience for sure.
