Why is the uncertainty in astronomers' knowledge of a star's distance greater for stars that are farther from earth?

I believe that it is all to do with margin of error. The further away the planet, the greater the margin of error in the observations and therefore the greater the uncertainty in their distance from Earth.

How much farther is the sun from earth than the moon from earth?
Find the distance from the earth to the moon, then the the distance from the earth to the sun, and simply subtract the both.
How is the distance of a planet from the sun related to its period of revolution?
The farther it is from the sun the longer its period of revolution (its "year").
What did astronomers Edwin Hubble discover that led to the formulation of his law?
Basically, his discovery was that most galaxies move away from us; and that the galaxies that are farther away, also tend to move away faster.
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.
Why is Mars cold?
Mars is cold mostly because it is farther from the sun than Earth is.
What did she trade him for this knowledge?

Why are scientists unsure of the distance of Deneb from Earth?
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.
What is maximum distance?
this means you cant go another farther. your equation will not allow you to compute any more numbers farther than the maximum distance.
Is it farther from Nevada to Wyoming than it is from Colorado to Illinois?
No, the distance from Colorado to Illinois is farther.
What is the difference of farther and further?
Farther for physical distance and further for a figurative distance... I am going farther than this, meaning for more miles yet I can not go any further than this, meaning I stop here, can not go on
Is farther an adjective?
It can be, when it modifies a noun (e.g. a farther distance) as the comparative of the adjective "far."It can also be an adverb (go farther) meaning "further."
Which is farther Spain or belgium?
I am sorry but we can't answer because we don't know the point of where you started in distance. Farther from what?
What is the distance between StPaul and Buffalo?
buffalo is farther
How can you shoot from a farther distance?
Back up and practice.
How do astronomers use pictures of distancee galaxies to determine the age of the universe?
The general tendency is for galaxies that are farther away from us, to move away from us faster. This can give a rough idea of a galaxy's distance, just by observing its redshift (which is a measure of how fast it moves away from us).
Is mars the same distance from the sun to earth?
Going to the sun is farther. :)
Is London or Paris farther from the United states?
They're about the same distance.
