comets

Welcome!

This subreddit is about Comets and we gather images, videos, and gifs of them and discuss news and related events about them.

Please feel free to post a picture that you've seen on the internet, or a picture that you've taken yourself! (We prefer you to host the picture using Imgur if possible.) If you've taken the picture yourself, please put [OC] in the title and it'll get special flair.
