Your friend argues that all the stars in a typical constellation are approximately the same distance from Earth. Is your friend correct?
150 million kilometers
the apparent difference in the position of an object when viewed from different lines of sight
declination and right ascension
No. The stars in a constellation fall within the same area on the celestial sphere, but some stars are closer to Earth.
six AU
Each eye views the coat hanger in a different line of sight. So, opening one eye, closing the other, the coat hanger moves.
both A and B
No. Parallax cannot be used to calculate the distances of objects more than approximately 300 light-years away.
At the eye doctor, you place a paddle over your left eye to read the eye chart. When you repeat the process with the right eye, you notice that the coat hanger in your peripheral vision has shifted. Explain what has happened in terms of parallax.
