The meme asks a very relevant question: why doesn't the sun have a visible tail?

Edited by moist nana: 3/30/2017 5:31:28 AMBecause the sun has a MUCH higher escape velocity than a coment. I couldn't throw a bunch of confetti in the air and expect it to form a trail behind Earth. Earth has too much mass/gravity, it would just fall back down. On a small rock in space, with nexto no gravity, it might just get flung out into space forming a trail.
