25 inches in circumference would be the largest normal (not  hydrocephalic) head.    The world record holder is Rick Walters.
Trending Now. Answers. Best Answer: 365 days, 5 hours, 49 minutes and 1.20 seconds (or 365.242375 days). The distance is not so easy; the Earth doesn't travel in a circle through space. With relation to the Sun, it does, but since the Sun is moving, the Earth moves in a helixal orbit.
The closer a planet is to the sun, the shorter the time to complete one revolution is. Mercury, for example, has an orbital period of 88 days while it takes Jupiter about 11.86 years. The period of the Earth's orbit is usually thought to be 365 days as calendars show. However when averaged it is actually about 365.25 days, which requires an extra day on the calendar every four years (causing a leap year). Contradictions within orbit times are probably caused by the ages of the sources.
