That's actually an interesting question. What truncations of the base10 digits pi are prime? There's 31 and 314159, but are those literally the only two options?

Actually, I wonder if he could calculate pi by tracking matt parker's position at two points in time? The asteroid of course.

[@ckq]

@@blak4831i'd imagine the telescopes use pi already

[@sebastians7869]

@@blak4831 That's an interesting thought. I think that you would probably need more than two data points on the position of the asteroid to get a calculation for pi. The perimeter of an ellipse is pretty much unrelated to pi--also covered in a video on this channel--so we would have to use the area of the orbit. After a quick Google search, apparently you need FIVE points on an ellipse to completely determine its equation. So maybe you could do it like this: five reasonably spaced observations --> approximate ellipse equation --> area --> pi

And for much about our solar system. Jupiter is like the plentary foreman that brought everything into alignment.

@@jeffspaulding9834 I never heard that one before. It does seem unlikely. Geological evidence shows that Earth and The Moon are made of the same stuff. The leading theory is that another planet, called Thea, slammed into Earth causing Earth to receive its current tilt, a ring system which then coalesced into a moon that continues to move away from us, and two large blobs of different density deep inside Earth that are thought to be remnants of Thea. There are some who disagree with this. It's thought that Thea's orbit may have been disrupted by Jupiter, causing the collision.
