How did the 5 pointed shape of what we call a star come to be?

I believe it had something to do with a kid with a lot of time and a spirograph.

The pentagram (or, “star”) is a shape that exists in nature, as in starfish, arrangement of seeds inside fruit, etc. So I wouldn’t say anyone other than Mother Nature invented the shape. I think the pentagram became associated with astronomical stars because when stars twinkle, they project rays of light that form a star-like shape.

I thought this looked cool:

I think it was invented by some grade school teacher!

@peedub—An excellent article on the Star shape, but nothing about why it is associated with an actual star.—That’s a good question, to me, stars look like round circles with four or more rays of light, more like a +.
