    The Supermoon Is A Lie

    Today's moon is a little bit bigger and a little bit brighter than normal, but you probably won't be able to see that with your eyes, sorry.

    By now you have probably heard about today's supermoon.

    It happens because the moon's orbit around Earth isn't a perfect circle, so sometimes it's further away from us, and sometimes it's closer.

    But remember: The change in distance (and therefore size) happens gradually over the month, so it's not like the moon is going to appear much bigger today than it did yesterday.

    The moon is so far away and so small in the sky that, even when it's a supermoon, you're unlikely to be able to detect any change by eye.

    Astronomer Phil Plait explained on Slate in 2013:

    While this is technically true, you’d never notice the difference in size or brightness by eye. The full Moon will look pretty much like every other full Moon you’ve ever seen. Which is to say, big, bright, beautiful, and completely worth your time to outside and see! But Supermoon? Not so much.

    So all those photos you've seen of the moon close to the horizon, looming over Earth? The moon doesn't look bigger in them because of the supermoon – it's a photography trick.

    And when you're looking with your own eyes at the supermoon coming up over the horizon, there's also the Moon Illusion at play.

    In conclusion: RIP the supermoon, long live the regular moon, which is almost as bright and just as beautiful. 🌕
