On the contrary, if the parallax angle is too small, it can't be measured accurately.
no, they're 90 degrees or less. a way to remember is aCUTE angle. a small angle is sorta cute right?
It depends on your definition of small and large. Obtuse angles are ones that are more than 90 degrees and acute angles are less than 90 degrees. If you forgive the bad graphics.. Obtuse: \_ Acute: /_
You can use cups to measure a small can of juice.
Line up the vertex, then if it is an acute angle use the small number, obtuse use the big number, next all you have to do is bring your finger up to where the angle line is and see what number, big or small it lines up with on the protractor!
The parallax angle of such distant objects is way too small to be measured. In general, the farther away an object, the smaller is its parallax angle.
they couldn't measure small angles
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.
Pressumably, they didn't have the high-precision devices required to measure those angles. You must consider that we are talking about extremely small angles - even the closest star has a parallax of less than one arc-second (1/3600 of a degree).
It means that the distance is greater than a certain amount - depending on how precisely you can measure the parallax.
A parallax is hard to measure if it is very small - and this happens when the corresponding object is very far away.
At larger distance, the parallax becomes smaller, and therefore harder to measure. Even the closest star (Toliman) has a parallax of less than one arc-second (1/3600 of a degree), which is difficult to measure. Stars that are farther away have a much smaller parallax.

The answer is: yes, just about, maybe. Astronomers had catalogued over 2 million stars with parallax values. However many of the values are estimates and some of the angles are very small.
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.
You can conclude that it is farther than a certain distance. How much this distance is depends, of course, on how accurately the parallax angle can be measured.
