Explanation:
Today Comet Wirtanen passes by the Earth.
The kilometer-sized dirty snowball orbits the Sun every 5.4 years,
ranging as far out as
Jupiter and as close in as the
Earth.
Today
Comet 46P/Wirtanen passes within only
31 lunar distances to the Earth, the closest approach in 70 years.
If you know
where to look (Taurus),
you can see
the comet through binoculars as an unusual
blue smudge.
Pictured
a week ago,
Comet Wirtanen was photographed in the sky beyond an old abandoned church in
Skagen,
Denmark.
The image composite also captures the astrophotographer.
After
today, the comet will begin to fade as
it recedes from the Earth and the Sun.
