It’s official: the Sun is the most perfect natural sphere ever measured
The Earth is not round, but the Sun — contrary to long-standing scientific belief — is a different story.
To be clear: the Earth certainly isn’t flat, but it’s definitely not a perfect sphere. Technically speaking, it’s an oblate spheroid — a sphere that’s been squashed, such that the distance from Earth’s center to sea level is about 13 miles greater at the equator than at its poles. Earth isn’t really smooth, either; in actuality, it’s kind of bumpy.
