Mars To Encounter Comet Siding Spring

By Dr. Lisa Will
 
This Sunday, October 19, Mars will have a close encounter with Comet Siding Spring.
 
And by close, I mean close!
 
Comet Siding Spring, also known as C/2013 A1, will be approximately 82,000 miles away from Mars at its closest approach. That might not seem like much, but to give you a sense of scale that is equivalent to about one-third the distance between the Earth and the Moon!

A comet streaks through the sky

By Dr. Lisa Will, Fleet Astronomer

Comet ISON is getting brighter in the sky, and it should hopefully become visible to the naked eye soon. If you want to know where to locate it in the sky or learn more about Comet ISON, some useful resources are listed below. 

Plus, the Fleet is hosting a Coffee & Comets event on Tuesday, November 26, early in the morning (because the comet can be viewed before sunrise). Visit our Events page for more information.
