25 inches in circumference would be the largest normal (not  hydrocephalic) head.    The world record holder is Rick Walters.

The length of time it takes for an orbit is equal to 164.79 Earth years. The distance traveled in its orbit can be computed from the orbital speed, and is approximately 28.24 â¦ billion kilometers. The average orbital radius (distance from the Sun) is 4.5 billion kilometers. 2 people found this useful.f the Earth's orbit were a circle, the length of the orbit would be the circumference, C=2 pi r. 2 * pi * (149 600 000 kilometers) = 939 964 522 kilometers Since the orbit is more nearly an ellipses, we could approximate the circumference as C= pi (a+b), but that does not actually improve the accuracy.
