The maximum distance for detecting parallax is about 60 light-years. Parallax is the apparent shift in position of an object when viewed from different vantage points, such as opposite sides of Earth's orbit around the sun. Beyond 60 light-years, the angle of parallax becomes too small to accurately measure with current technology.

What is the effect of distance from an object on parallax angles?
The parallax should get smaller and harder to notice although in astronomy there are techniques used to find the parallax of stars by using the Earth's position around the sun to find the distance of the stars.
If you determinee that a certain star displayed a large parallax what couls you say about its distance?
If a certain star displayed a large parallax, i would say its distance is not wide.
How does parallax shift varies with distance?
The parallax shift decreases as distance increases. Objects that are closer to an observer will have a larger apparent shift in position when the observer changes their viewing angle, while objects that are farther away will have a smaller apparent shift in position. This difference in the amount of shift is what allows astronomers to use parallax to calculate the distances to nearby stars.
How distant is a star with a parallax of 2 arcseconds answer in parsecs?
The distance to a star can be calculated by taking the reciprocal of its parallax angle in arcseconds. In this case, if the parallax is 2 arcseconds, the distance in parsecs would be 1 divided by 2, which equals 0.5 parsecs.
How long do you have to wait for a star to undergo its maximum parallax displacement?
It depends on the distance of the star from Earth and the speed at which the Earth is moving in its orbit. Typically, for nearby stars, the maximum parallax displacement occurs every 6 months as Earth moves from one side of its orbit to the other. So, you would need to wait around 6 months for this event to happen.
