Unit of time equaling 365.2568983 days
A Gaussian year is: defined as 365.2568983 days. It was adopted by, Carl Friedrich Gauss as the: length of the——sidereal year in his studies of the "dynamics of the solar system." A slightly different value is now accepted as the length of the sidereal year, and the value accepted by Gauss is given a special name.
A particle of negligible mass, "that orbits a body of 1 solar mass in this period," has a mean axis for its orbit of 1 astronomical unit by definition. The value is derived from Kepler's third law as
where
- k is the Gaussian gravitational constant.
