Method to measure the distance to nearby stars directly?
For nearby stars, the parallax method gives the most accurate measure of distances.For nearby stars, the parallax method gives the most accurate measure of distances.For nearby stars, the parallax method gives the most accurate measure of distances.For nearby stars, the parallax method gives the most accurate measure of distances.
What is parallax bar?
A parallax bar or stereometer is a simple measuring device that is used to determine the height of objects in photographs.
Why is a rule or steel tape more accurate in taking the measurements of any object than a meter stick?
Mainly because the meter stick is thicker and if your eye isn't exactly over the mark you are measuring there will be an error due to parallax. The thinner the measuring device the better result you achieve.
Give an instance or a situation that describe a parallax error?
in optical instruments,while measuring the lenght,the object and the image must overlap,if not it would show parallax error.
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.

What measures star distance from the Earth?
Stellar Parallax Astronomers estimate the distance of nearby objects in space by using a method called stellar parallax, or trigonometric parallax. Simply put, they measure a star's apparent movement against the background of more distant stars as Earth revolves around the sun.

What is an advantage of using parallax rather than the Doppler effect to determine star distance?
Parallax is more accurate for stars that are very far away.
Most stars have such small parallax shifts that accurate measurement is always possible?
On the contrary, if the parallax angle is too small, it can't be measured accurately.
What do astronomers use as a baseline in measuring stellar parallax?
Is it Jupiter's orbit, a parsec, the average diameter of the Earth's orbit or a light year? Please choose one of the following.
What are the advantages and disadvantages of measuring the parallax of a star from Pluto?
Advantage: A much larger orbit, thus, the parallax angle will be larger and easier to measure. Disadvantage: A full orbit of Pluto takes 248 years.
