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.

A Closer Look at Some Comets that will reach Perihelion in 2013

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 became visible to the naked eye in 2013 or were otherwise newsworthy.



Comet PANSTARRS could refer to any one of the hundreds of comets discovered by the Panoramic Survey Telescope and Rapid Response System atop Haleakala in Maui. One of its discoveries (C/2011 L4) was a naked-eye comet visible in both the southern and northern hemisphere in early 2013.
Comet Lemmon    
The Mt. Lemmon Survey (MLSS) has discovered more Potentially Hazardous Asteroids (PHAs) than any telescope on Earth. MLSS has also discovered comets. On March 23, 2012 images from MLSS captured a 20.7 magnitude comet (C/2012 F6). It reached perihlelion on March 24, 2013.
Comet Encke    
Comet Encke (2P/Encke) orbits our Sun once every 3.3 years, which is the quickest known orbit of any comet. The Taurids and Beta Taurids, which are meteor showers occuring each November and June, are believed to be the remains of the dust trail left by Comet Encke. Binoculars could be used to spot this comet, before its perihelion, beginning in late September of 2013.
Comet ISON    

On September 24, 2012 it was announced that we had a 2 mile (3 km) wide visitor in our solar system between Jupiter and Saturn in the constellation of Cancer. Comet ISON (C/2012 S1) had the potential to be as bright as a full moon in early December of 2013...if it could survive perihelion on November 28, 2013. Unfortunately it did not. The vast majority of the comet's nucleus evaporated in the Sun's corona.


SOHO Comets    

Dozens of tiny comets, known as sungrazers or sunskirters, returned to tightly orbit the Sun in 2013, but they were only be visible from space observatories like SOHO and LASCO. The general public can comb through movies and images captured by SOHO, attempting to discover the next comet. It's not as impossible as it sounds, a comet is discovered every three days on average.
