Parallax would be easier to measure if the Earth were farther from the sun. This way, there will be a wider angle to the stars using the parallax method.

You need to measure it with something flexible, like a string.If you know for sure it is a circle, it would be easier to measure the diameter, then multiply by pi.

The difference between an actual correct view and a displaced visual parallax error

Depends on what measurement standard you are using and what field you are referring to. It is easier tlo measure in kilograms because it involves smaller numbers. However, if you were studying astronomy, you would likely measure the dog in grams, or solar masses.

Yards. Lakes are pretty big, and yards is a larger measurement than feet so yards would be an easier measurement.

On the contrary, if the parallax angle is too small, it can't be measured accurately.

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.

Advantage: A much larger orbit, thus, the parallax angle will be larger and easier to measure. Disadvantage: A full orbit of Pluto takes 248 years.

It's distance

A parallax is hard to measure if it is very small - and this happens when the corresponding object is very far away.

Parallax bars are used in photogrammetry and remote sensing. with the use of the principles of parallax and refraction, parallax bars are used to measure the heights of buildings and other features.

The farther the object, the smaller its parallax. In this case, the parallax is about 1/300,000 of an arc-second (and an arc-second is 1/3600 of a degree) - way too small to measure. Perhaps you will eventually find a way to measure smaller parallax angles.

At farther distances, the parallax becomes too small to measure accurately. At a distance of 1 parsec, a star would have a parallax of 1 second (1/3600 of a degree). (The closest star, Toliman, is a little farther than that.) At a distance of 100 parsecs, the parallax is only 1/100 of a second.

The closer the star, the greater the parallax angle, which is why you can't measure the distance to very distant stars using the parallax method.

The parallax refers to the apparent change in the star's position, due to Earth's movement around the Sun. This parallax can be used to measure the distance to nearby stars (the closer the star, the larger will its parallax be).

It means that the distance is greater than a certain amount - depending on how precisely you can measure the parallax.
