Radius of sun au
Web1. In the 1800's the AU was connected to: the time average of 1 divided by the Earth-Sun, and that is the reason Gauss's constant occurred (until 2012) in the calculation of the AU. The reciprocal of the distance was used because it has less of a linear tread and also because it is not as dependent on the eccentricity (which has a large ~linear ... WebThe astronomical unit (symbol: au, [1] [2] [3] [4] or AU or AU) is a unit of length, roughly the distance from Earth to the Sun and approximately equal to 150 million kilometres (93 million miles) or 8.3 light-minutes.
