TL;DR The Christmas Comet will pass by Canada on December 16th and is expected to be the brightest comet of the year.

Comet 46P/Wirtanen was looking incredible last night from the Bighorn Mountains of Wyoming. It’s already naked eye visible and will get even brighter next week at closest approach.

Named after the American astronomer, Carl Wirtanen, who first discovered it in 1948, the comet is one of very few that is visible with the naked eye from Earth.

It is also one of only ten comets that have made their closest approaches to earth in modern history. 

The "Christmas Comet" will make its closest approach to earth in over 70 years, meaning it should be super bright and visible all night.

On December 16, Comet Wirtanen will swing by Earth, closer to us than it's ever been in the last 400 years. Learn more >>

Even cooler is that the resulting debris coming off a comet this size can often spark a meteor shower!

The comet could be visible as early as December 13th, but should continue to be visible in the Northern hemisphere until the beginning of January.
