... 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 CELESTIAL SPHERE
... 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 ...
