For a comet I'd probably first try a media solution.
I played some with a blob based, 2D image processing framework in early
2016 which might do for a 2D motion blur effect(1). See:
http://news.povray.org/povray.binaries.images/thread/%3C56ca69e1%40news.povray.org%3E
POV-Ray can duplicate pretty much any 2D gimp/photshop result. However,
given it's a 3D rendering tool and so carries extra overhead - it's
almost always slower than a 2D/2.5D alternative. A way of saying a 2D,
layer based, image tool might be the expedient path - especially if it
already has the canned effect you want.
Some have implemented motion blur by blending multiple images from an
animation of the moving parts into a single final image. This can be
done entirely with POV-Ray today though not in a single render.

(1) - A comet is a moving object where you don't need the associated
blurred shadows, reflections, an uberpov 'blink' like feature offers.
