Parallax is the difference in observed angle (position) between two observations that are taken at two different points. The most common use of parallax is in measuring the positions of stars 6 months apart, when the Earth is 186 million miles from its starting point. By using trigonometry, and comparing against the far distant (constant) stars, you can then estimate the distance to the (nearer) star.

What is the size of an astronomical parsec?
By definition, if the parallax is one arc-second (1/3600 of a degree), the distance is one parsec.By definition, if the parallax is one arc-second (1/3600 of a degree), the distance is one parsec.By definition, if the parallax is one arc-second (1/3600 of a degree), the distance is one parsec.By definition, if the parallax is one arc-second (1/3600 of a degree), the distance is one parsec.
An object that is farther away than another object will have a parallax?
Yes, objects that are farther away than others will exhibit less parallax. Parallax is the apparent change in position of an object when viewed from different perspectives. The closer an object is, the greater its parallax when viewed from different angles.
Which star would have a greater parallax the earth or the arcturus?
Earth isn't a star and doesn't (can't) have a parallax, becuse we use Earth's orbit as a baseline to measure parallax.
How is a parallax helpful to astronomers?
Parallax is the apparent change in postion of an object when looked at from two different places. Astronomers use parallax to find how far away nearby stars are.
If a star has a parallax of 0.20 arc seconds what is the distance to that star?
The distance to the star can be calculated using the formula: distance (parsecs) = 1 / parallax angle (arc seconds). Plugging in the given parallax of 0.20 arc seconds, the distance to the star would be 1 / 0.20 = 5 parsecs.
What a parallax?
The definition for the word parallax is "the effect whereby the position or direction of an object appears to differ when viewed from different positions, e.g., through the viewfinder and the lens of a camera."

A distortion to a measurement caused by the angle at which the measurement is taken is called?
Survey ANS #2: That is the definition of "Parallax". Parallax is what causes the gas gage on a car to appear empty to the passenger when the driver sees that it still reads a quarter of a tank.
