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

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.
Astronomers measure the parallax angle of a planet or star to determine its distance from Earth. By observing the apparent shift in position of the object against the background stars as the Earth orbits the Sun, astronomers can calculate the angle and use it to estimate the object's distance.
Parallax can be used to measure a star's distance from Earth by observing the apparent shift in the star's position against a background of more distant stars as Earth orbits the Sun. This phenomenon occurs because the observer's viewpoint changes, creating a small angular displacement known as parallax angle. By measuring this angle and applying trigonometric principles, astronomers can calculate the distance to the star in parsecs. The formula used is Distance (in parsecs) = 1 / parallax angle (in arcseconds).
The distance to a star can be determined using the measure of parallax by observing the star from two different points in Earth's orbit around the Sun. By measuring the apparent shift in the star's position against more distant background stars, astronomers can calculate the star's distance based on the angle of the parallax.
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.
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.
There is an uncertainty in ANY distance calculation; more so in astronomy, where you can't apply a measuring tape directly. For example, if you use the parallax method, you can only measure the parallax angle up to a certain precision; the farther the star is from us, the smaller the parallax angle, and therefore the larger will the uncertainty be.Specifically in the case of Deneb, it seems that it is surrounded by a shell of material; this makes it more difficult to measure the parallax exactly.
Parallax is the apparent shift in the position of an object when viewed from different angles. In astronomy, parallax is used to measure the distance to stars by observing how their positions change as the Earth orbits the Sun. By measuring the angle of the shift, scientists can calculate the distance to the star using trigonometry.
The apparent movement of a star used to measure its distance from Earth is called parallax. Astronomers observe how a star's position changes relative to more distant stars as Earth orbits the Sun, allowing them to calculate the star's distance based on the angle of this shift.
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.
