Given the inverse relationship between parallax and a star's distance, order the stars from closest to farthest.
Which object is farthest from Earth?
The inverse square law states that the apparent brightness (B) of a star decreases with the square of the distance (d) : B∝(1)/(d^2) If a star's brightness at 1 parsec is 9 units, what would its brightness be at 3 parsecs?
