A Bright Green ‘Christmas Comet’ Will Fly The Closest To Earth Tonight and Won't Be This Close Again For Thousands of Years
Tonight, look up at the night sky and you just might be lucky
enough to see a bright, blurry ball with a visible greenish-gray
shade. That greenish-gray shade object is a comet that orbits
between the Sun and Jupiter will make its nearest approach
to Earth in centuries. And this all will be happening right on the heels
of this year’s most beautiful meteor shower of 2018.


Tony Farnham, is a research scientist in the astronomy
department at the University of Maryland. He appeared on Saturday morning
after a long night observing the comet at the Discovery Channel
Telescope. Discovery Channel Telescope is located about 40 miles
southeast of Flagstaff, Ariz. Tony Farnham said “The fuzziness
is just because it’s a ball of gas basically,” “You’ve got a
one-kilometer solid nucleus in the middle, and gas is going out hundreds of
thousands of miles.”

The Green Comet 46P appears green due to the
gases it emits light. The ball of gas and
dust, also called as the “Christmas comet,”
was nicknamed 46P/Wirtanen, after the astronomer Carl Wirtanen,
who found it back in 1948. It circles the sun once every
5.4 Earth years It passes by Earth roughly every 11
years, but its distance alter and it is rarely this close.

The closeness of 46P/Wirtanen give astronomers a chance
to study the tail of the comet and see farther into the
nucleus. This amazing article by Rao will help you get more
information about where to look, depending on when you are able to go outside
for the show. Tonight it will be its closest approach to the Earth in 20 years.
And it won’t be this close again for centuries or perhaps even in a thousand
years.
