You can now buy the recently released book, Fall of a Thousand Suns: How Near Misses and Comet Impacts affected the Religious Beliefs of our Ancestors. It is available through iBooks and Amazon.


This website only lists information on modern-day comets and meteor showers. The book, however, thoroughly investigates how specific ancient impacts and near misses changed religious beliefs around the world.

Comets in 2015

Between one hundred billion and two trillion comets are thought to exist in our solar system. As of April 18, 2015, only 3,845 comets have been observed and named. Let's take a closer look at some comets that may be visible to the naked eye in 2015 or are otherwise newsworthy.



Comet Pons-Winnecke    
Pons-Winnecke is a Near Earth Comet (NEC). In 1927, Pons-Winnecke was .0394 AU from Earth. That's roughly fifteen times the distance between the Earth and the Moon. It will be the first comet to reach perihelion in 2015.
Comet d'Arret    
This comet was discovered and recorded by Heinrich Ludwig d' Arrest in Leipzig, Germany on June 28, 1851. It was the sixth comet to have its periodic orbit determined and therefore received the formal name of 6D/d'Arrest. This comet only has an orbital period of 6.54 years, so we won't have to wait too long for this comet after 2015.
Comet Churyumov-Gerasimenko    
In November 2014, The European Space Agency plans to release a lander, called Philae, from its Rosetta Spacecraft. The lander will attach to the surface of Comet 67P/Churyumov-Gerasimenko. It will study the comet before, during, and after its closet approach to the Sun on August 13, 2015.
SOHO Comets    

Dozens of tiny comets will closely orbit the Sun in 2015. The vast majority will die in its corona or on its surface. Only space observatories using coronagraphs, like SOHO, will be able to observe these comets. The general public has access to SOHO's movies and images, and can attempt to discover comets in 2015.
