... The diameter of Alpha Centauri A is 1.71 x 109 meters. The Sun’s diameter is 1.39 x 109 meters as determined from the table in the text’s appendix. Thus, Alpha Centauri A is slightly larger than the Sun with a diameter of 1.23 solar diameters. Alpha Centauri B is (60/85) = 0.706 times smaller than A ...

... The stars are at a very large distance from us. So the relative movement between them is of no consequence to day-to-day observations. We therefore imagine the stars to remain fixed on a sphere of very large radius with the earth at its centre. We call this sphere the celestial sphere. At any point ...

Astronomical unit

The astronomical unit (symbol au, AU or ua) is a unit of length, roughly the distance from the Earth to the Sun. However, that distance varies as the Earth orbits the Sun, from a maximum (aphelion) to a minimum (perihelion) and back again once a year. Originally conceived as the average of Earth's aphelion and perihelion, it is now defined as exactly 7011149597870700000♠149597870700 meters (about 150 million kilometers, or 93 million miles). The astronomical unit is used primarily as a convenient yardstick for measuring distances within the Solar System or around other stars. However, it is also a fundamental component in the definition of another unit of astronomical length, the parsec.
