Web29 aug. 2024 · Sirius has a parallax of 0.37921 arcseconds. To calculate the distance, in terms of light-years, we use the equation introduced earlier: d (parsec) = 1/p (arcsecond) Distance = 1/0.37921 = 2.637 parsecs. To convert from parsecs into light-years this result must be multiplied by 3.26. Distance to α Canis Major = 2.637 x 3.26 = 8.6 light-years. cir law offices llp san diego

The Earth is not stationary, it moves in a 150 million km (1 AU) radius orbit around the Sun. If you measure the apparent position of a star at different points in that orbit a near enough object will appear to be displaced by a measurable amount, this displacement is called parallax, which is typically measured across a 1 AU baseline.
