What is the roundest natural object in the universe?

That is an interesting factoid, although I am uncertain as to why it would have been believed to not having been spherical. Still, there is another issue: why, if it is that close to being spherical, is it not *perfectly* so. What causes this infinitesimal deviation from perfect symmetry? And is it a bulge (oblate spheroid) or a narrowness (cigar shape) deviation? What is special about the axis that is different from the others?

Unless it is that the deviation is less than the quoted value, which cannot be measured more accurately, so it could be perfectly spherical after all...

Steve4Physics: read again, it says *if it were magnified to the size of the solar system* then it would be less than a human hair out of being spherical.

Roundest Object

Interesting article. But it says ... "making it spherical to within the breadth of a human hair."

That's plain silly, because an electron is so much smaller than a human hair to start with!

As far as wer know, the electron.

There are no degrees of roundness. Something cannot be rounder than something else. It is either round or not.
