The closer the star, the greater the parallax angle, which is why you can't measure the distance to very distant stars using the parallax method.

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.
What is a parsac?
I'm not sure what a "parsac" is, but "parsec" is the shortcut name for "PARallax SECond of arc", the distance away from the Sun where another object would appear to have an angular parallax shift of one arc-second as compared to the distant background stars. It is approximately equal to 3.26 light-years.
How is the distance measured of stars less than 1000 light years away?
The parallax method is usually used in this case. Earth's movement in its orbit cause an apparent shift in position in such a star.
Do scientists use stellar parallax to determine a star's temperature?
Not if they have the faintest clue what they're doing. Parallax is used to measure distance, not temperature.
Is the larger a parallax shift the closer an object is?
Yes, that's the way it works. A parallax angle of 1" (arc-second) means that the object is at a distance of 1 parsec (that's how the parsec is defined); at a parallax angle of 1/10 of an arc-second, the object would be at a distance of 10 parsec, etc. A parsec is approximately 3.26 light-years.
What is the apparent shift in measurement is called?
parallax
Distance to nearby stars can be determined from?
stellar parallax
The apparent shift in the position of nearby stars when compared to distant stars is?
Doug Fany answer: Parallax
How can parallax be used to determine the distance to nearby stars?
The reciprocal of the parallax is taken. For example, if the stellar parallax is 1 second, the distance is 1/1 = 1 parsec; if the parallax is 0.1 second, the distance is 1/0.1 = 10 parsecs, etc.
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 ca parallax calculate?
Distance.
What can parallax calculate?
Distance (to an object).
What is the apparent shift of stars as earth orbits the sun?
parallax :)
What is a star's apparent shift in motion called?
Motion parallax.
The apparent westward movement of a planet against the background of stars is called?
"Parallax shift". We can't SEE the difference in position of any star as seen from the Earth 6 months later or earlier, but by measuring the very tiny differences in the positions of the more distant stars, we can observe the "parallax" of a star and thus calculate its distance. This only works for stars less than about 300 light years from Earth.
How is a parallax used in astronomy?
for determining distance
