Inbound from the Oort Cloud, its ion tail is a shade of pretty blue.

Wow you are an total idiot aren't you.... When the something is closer
in the foreground than it is in the background that means that is
moving AWAY from you..... Or were you too fucking stupid to realize
that?

A comet's tail always trails away from the Sun
regardless of the trajectory of the comet itself.

AA No that is not always correct. A comet DOES NOT always have a tail
produced by the sun and when a comet goes around the sun one of its
tails is pointing at the sun, or at least behind the comet which would
be towards the sun or at least in its general direction

Um, both the ion tail and the dust tail are swept behind it relative
to the sun, pushed by the solar wind.

If you have any photos of comets demonstrating anything otherwise, I would be
interested in seeing them.

No it does NOT..... If part of an object is bigger that means it is
closer

No it does not, You are an incredible fucking moron..... When a comet
is in the oort cloud it only has 1 tail and it is not a tail produced
by the sun. You are such a fucking moron.

Yes it does.

I always appreciate your kind remarks.
When a comet is in the oort cloud it only has 1 tail
and it is not a tail produced by the sun.
Have you ever seen one in the Oort Cloud?

A comet doesn't have a tail in the Oort cloud. The temps are too low
out there to cause the various ices to vaporize.

I think Andrew's subject line may be confusing. We are not
seeing this object "in the Oort cloud". We can't even see
the Oort cloud -- dark objects 100,000 AUs away from us.
It's a hypothesis, one that makes sense of phenomena, but
not something that has been directly observed.

At the time the photo was taken, the object was 3 AUs out,
somewhere between the orbits of Mars and Jupiter.

Andrew took the line "inbound from the Oort could" from the
description at the Astronomy Picture of the Day's site. I'd
suggest he might want to leave the descriptions on in the future.
