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 2017


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 2017 or are otherwise newsworthy.



Comet Encke    
Comet Encke (2P/Encke) orbits our Sun once every 3.3 years, which is the quickest known orbit of any comet. Meteor showers, known as the Taurids and Beta Taurids, are thought to be the remains of the dust trail left by Comet Encke. There are even theories that the Tunguska explosion in 1908 was created by a small piece of Comet Encke.
SOHO Comets    

Dozens of tiny comets will closely orbit the Sun in 2017. 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 2017.





A List of all Comets that will reach Perihelion in 2017

All comets no matter how faint, provided they reach perihelion in 2017, are listed below alongside the day of discovery, perihelion, orbital period, diameter and apparent magnitude. Each column is sortable. Simply click on the arrows at the top of each column.
