How crazy is it that the sun and moon appear to be the same size in the sky?

The sun’s diameter is about 400 times that of the moon, and also about 400 times further away, making them appear to be the same size to us.

That’s just one of those fascinating coincidences that makes a total eclipse so stunning visually. If the apparent diameters weren’t the same we would never have a total solar eclipse. At least one where the suns chromosphere and corona are visible. If you ever get a chance to see one go do it. It’s not often you can see the suns corona playing in its magnetic fields. You also get to see the two inferior planets if you’re lucky.

Is it just a coincidence?

All is by design.


I don’t think so, as Robert said above it’s all by design. Everything from the perfect distance from the sun, the tilt of the earth, the current in the oceans is all by design.


Did you know the Moon is slowly moving away from the earth? The moon used to appear much closer when it was first formed, and according to this it might escape earth’s orbit in ~15 billion years (although it won’t get the chance, the inner planets will be swallowed by the sun in 6-7 billion years as it enters the red giant phase).

Still pretty cool that we’re here around to see it at just the right distance.

Or the most magical thing, that frozen water (unlike frozen other liquids) has less density than water, which allows it to float. If frozen water didn’t float, nothing on earth would be alive.


What’s crazy is to think how many other earth-like planets there must be out there. There is no doubt in my mind that intelligent life exists on many, many other planets. Hopefully we find one someday!

That’s called the Drake Equation.

Evening, Nick. Hope this post finds you, wife, and your rapidly growing young family are well and in good humor tonight.

To elaborate further on your observation, “at this particular moment in Earth’s history – although the sun’s diameter is about 400 times larger than that of the moon – the sun is also about 400 times farther away. So the sun and moon appear nearly the same size.”
Hope that helps.

I really suggest everyone finds a legit observatory to visit on a clear night. Seeing another planet clearly with your own eyes is unbelievable. I saw Saturn up close once a 20” diameter telescope in the NJ meadowlands and it’s honestly a little life changing. Hard to wrap your mind around the concept of other planets by just looking at images.

Going to the UT McDonald Observatory out near Big Bend National Park is on my bucket list. They have a gigantic 82” diameter scope that you can reserve viewing sessions on for $150, but you have to book it months out. They also have solar scopes that you can look directly at the sun with.

It is also the only substance that expands when it freezes, AND when it heats

Made from two high-energy gasses. Water is so weird.
