| Final Question | |
From Earth, star Y appears to be the brightest, while star X and star Z appear to be similar in brightness. List the order of the stars from closest to farthest from Earth and explain your thinking. |
Star Y is the clsosest because it appears brightest and it is the smallest. Star Z is next because it appears as bright as star X even though star X is larger.
From Earth Y, Z, X |
