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 can parallax be used to measure a star's?
Parallax is used to measure a star's distance by observing its apparent shift in position against more distant background stars as Earth orbits the Sun. This shift, known as parallax angle, is measured in arcseconds. By applying the formula ( d = \frac{1}{p} ), where ( d ) is the distance in parsecs and ( p ) is the parallax angle in arcseconds, astronomers can calculate the distance to the star. The smaller the parallax angle, the farther away the star is from Earth.
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 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.

What ca parallax calculate?
Distance.
What can parallax calculate?
Distance (to an object).
If a star has a parallax of 0.20 arc seconds what is the distance to that star?
I assume you mean the parallax. If the parallax is 0.1 arc-seconds, then the distance is 1 / 0.1 = 10 parsecs.I assume you mean the parallax. If the parallax is 0.1 arc-seconds, then the distance is 1 / 0.1 = 10 parsecs.I assume you mean the parallax. If the parallax is 0.1 arc-seconds, then the distance is 1 / 0.1 = 10 parsecs.I assume you mean the parallax. If the parallax is 0.1 arc-seconds, then the distance is 1 / 0.1 = 10 parsecs.
How is a parallax used in astronomy?
for determining distance

Is parallax a star?
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).
What effects doe lengthening the distance from the observer have on parallax?
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 a star's parallax angle is too small to measure what can you conclude about the stars distance from earth?
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.
If a star's parallax angle is too small to measure what can you conclude about the star's distance from earth?
It means that the distance is greater than a certain amount - depending on how precisely you can measure the parallax.
Why can parallax only be used to measure distance to star that are relatively close to earth?
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.
How can parallax be used to measure a star's?
