This is not a comet.

This is a star, and that tail is thirteen light-years long.

And it's travelling so fast it has a bow shock.

That's travelling at about about 0.000434C.

And is awesome. On several levels.

Hay! Relativity, people!

Where's the medium? You're not going to get a bow shock and a trail without resistance. Next you're going to tell me it's self propelled and accelerating! So what is the star plowing through? An invisible nebula? Dark matter? Gravitons? C'mon!

Honest-to-goodness shooting star? That is shit-hot!
