4-sd approximation is 108.4 trillion km
Explanation:
The 4-sd approximation in light years (ly) to the distance of the
binary star system of larger Procyan A and smaller Procyon B, in the
Northern Sky, is 11.46 ly.
1 light second (ls) =299792.58 km.
1 ly =(1 ls )X (1 year in seconds)
=(299792.458) X (365,256363 X 24 + 60 X 60) km
So, Procyon distance is
9.4609 X 11.46 trillion km
=108.4 trillion km, nearly.
Here, 1 trillion =
