…it looks suspiciously like it’s the same size as the sun. What the hell, right? Is it a conspiracy? Is the moon just the sun’s ‘CLOSED‘ sign? Well, it turns out it’s just astronomical coincidence, and it’s one that occasionally makes for some pretty spectacular events.

Let’s start with a couple of basics: D&D. No, not the dice-centric roleplaying game. D&D in this case are of the celestial variety: distance and diameter. Look at the sun. (Ed. note: No…stop that. Don’t look at the sun. It’s bad for your eyes. Jesus. I’ll be more specific.) CONSIDER the sun. It’s about 864,000 miles across, plus or minus the distance between Detroit and Chicago. That’s a lot of miles across the solar equator. But…the sun is also really far away. Like 93 million miles far.  In short, the sun is big and far.

Now, there’s the moon. Also big, also far. Just not as big or as far as the bright shiny thing you use to work on your summer tan. The moon’s diameter is a relatively tiny 2,160 miles across…basically the distance between Philadelphia and Salt Lake City – not even all the way across the continental US. But, it’s closer too. Much closer. Only a short 239,000 miles away (and moving farther away every day; but that’s a story for another time).

So, to sum up: Sun – big and far. Moon – less big and less far. But, there’s a proportional aspect. The sun 864,000 mile diameter is almost exactly 400 times bigger across than our moon (400.3415 times to be exact). However, the distance between the sun and the earth is 389 times the distance between you and the thing that makes tides AND werewolves.

And that ration of 389:400 is close enough so that our simple vision makes the two seem to be the same size, which in turn makes for really, really cool things like eclipses once in a while. The next really good one will be a total lunar eclipse Friday July 27th (2018), visible to our friends in on pretty much every continent EXCEPT north america. This site helps keep track of any upcoming astronomical events, like eclipses, meteor showers, rise of Cthulhu and the Dark Ones…you know, the usual space stuff.

LOOK TO THE SKIES. …except during the day, because that sh*t will make you blind.
