What Shape Is the Sun?

The sun is almost a perfectly round sphere. The sun is the one of the roundest natural objects ever measured, according to scientists at the University of Hawaii.

The sun is so round that if scaled to the size of a beach ball, the variation between the highest and lowest point would be the width of a human hair, as National Geographic indicates.

The sun is the largest object in the solar system. The sun has a circumference of 2,713,406 miles, and it could accommodate 109 Earths across its face. Volume-wise, 1.3 million Earths could fit inside of the sun.
