Which of the following best describes the difference between two different units of distance in space?
AU is useful for measuring distances in the solar system; a light-year is useful for measuring distance beyond solar system.
distance
declination and right ascension
25 light years
Each eye views the coat hanger in a different line of sight. So, opening one eye, closing the other, the coat hanger moves.
No. Parallax cannot be used to calculate the distances of objects more than approximately 300 light-years away.
Place a marble(Earth) on a table, and place an overturned glass bowl(celestial sphere) over the marble, mark stars, on bowl.
the apparent difference in the position of an object when viewed from different lines of sight
Vega, the brightest star in the constellation Lyra, has a parallax angle of approximately 0.13 arcseconds when viewed at 2 different times six months apart. Approximately how far away is Vega from the Sun?

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.
