Everything you need to know



Elenin is an average sized comet that was discovered by Russian astronomer Leonid Elenin on December 10, 2010.  It is also known as comet C/2010 X1. It is a long-period comet and takes about 10,000 years to complete one orbit around our Sun. 

The most recent prediction is Elenin will be closest to Earth sometime in September.  The exact trajectory of the comet still has some uncertainty.

There are many conspiracy theories regarding this comet.


Sometime around September, Elenin should reach magnitude 6.  Thats about the limit of what the human eye can see in really dark conditions.

21 Million Miles

Elenin will only get within about 21 million miles of Earth.  It is a ball of ice and dust particles, about one hundred billionth the mass of our moon.  That means its tidal pull on Earth will be equal to about one hundred trillionth of the Moon.
