: 1. My friend and I were confused about question #3. Couldn't a parsec be used to measure the distance of a star or the light travel time, since they are related? Isn't measuring in parsecs interchangeable with measuring in light-years? Could you clarify?
: 2. Do stars, planets, the sun and the moon all move from east to west across the sky? Can you explain question 25?
: Thank you for your help.
