Though what happens to it now, we catch up with it in around 50 years time, it is in an Earth trailing orbit.

Many of the images would make great wall art (I know it is a science thing first and more than pretty pictures, not an artists tool)

In other news, two satellites have a close encounter over Pittsburgh, didn't hit each other but there was no control. Too much junk up there.

One of those satellites wasn't just "any" satellite - it was IRAS, probably the most important space telescope before the Hubble.
