I've known that some meteor showers are better than others, but this makes it easy to tell visually with how dense/sparse each one appears.

This layout also made me wonder what would meteor showers look like from other planets. Mars has a thinner atmosphere, so maybe only larger debris would be visible?? But what about planets with thicker atmospheres?

Mars has a lot of dust in the atmopshere, which makes Martian astronomy more difficult. The Spirit rover did manage to capture an image of a comet though. There's some more detail on Wikipedia: https://en.wikipedia.org/wiki/Astronomy_on_Mars#Comets_and_m...

If you're interested in the concept of "alien astronomy" from other planets, I've used these "planetarium" style tools to play around with what it'd look like:
