There are various sorts of points, used in particular locations and times: * Fournier point: the first definition of the printer's point, by Pierre Fournier. It was 0.34882 millimetres, which was 1/12 of a cicero. Unit Definition (astronomical unit) An Astronomical Unit is approximately the mean distance between the Earth and the Sun. It is a derived constant and used to indicate distances within the solar system. Its formal definition is the radius of an unperturbed circular orbit a massless body would revolve about the sun in 2*(pi)/k days (i.e., 365.2568983.... days), where k is defined as the Gaussian constant exactly equal to 0.01720209895. Since an AU is based on radius of a circular orbit, one AU is actually slightly less than the average distance between the Earth and the Sun (approximately 150 million km or 93 million miles).
