Explanation:
Now approaching
our fair planet this Comet PanSTARRS (C/2013 X1)
will come closest on June 21-22, a mere 5.3
light-minutes away.
By then its appearance
low in northern hemisphere predawn skies (high in the south),
will be affected by the light of a nearly Full Moon, though.
Still the comet's pretty green coma is about the apparent
size of the Full Moon in
this
telescopic portrait,
captured on June 12 from the southern hemisphere's Siding Spring Observatory.
The deep image
also follows a broad, whitish dust tail
up and toward the left in the frame, sweeping away from the Sun
and trailing behind the comet's orbit.
Buffeted by the solar wind, a fainter, narrow ion tail
extends horizontally toward the right.
On the left edge, the brightest star is bluish Iota Picis Austrini.
Shining at about fourth magnitude, that star is visible to
the unaided eye in the constellation of the
Southern Fish.
