Did you ever sit in the passenger seat and look at the fuel gauge on the dash? You see the gauge from the side so it appears that the needle is pointing to Empty. The driver is looking straight at it so the driver sees the actual reading to be a quarter of a tank. That was a parallax error that your observation position created.
What else can I help you with?
Is a star with no measurable parallax is very close to Earth.?
No, if you can measure no parallax, the star is far away - further than a certain distance.
Is a star with no parralex very close to earth?
No. A star with no visible parallax is far away.
If a star's parallax is too small to measure does that mean that it is close or far from Earth?
If a star's parallax is too small to measure, it means that the star is far from Earth. Parallax measurements are used to determine the distance of nearby stars by observing their apparent shift in position as Earth orbits the Sun. Stars with large parallaxes are closer to Earth, while stars with small or undetectable parallaxes are further away.
If a star has a parallax of 0.232 how far is the star from the sun in parsecs?
The reciprocal - in other words, 1 / 0.232.
Parallax would be harder to measure if?
A parallax is hard to measure if it is very small - and this happens when the corresponding object is very far away.
Is a star with no measurable parallax is very close to Earth.?
No, if you can measure no parallax, the star is far away - further than a certain distance.
How is a parallax helpful to astronomers?
Parallax is the apparent change in postion of an object when looked at from two different places. Astronomers use parallax to find how far away nearby stars are.
Why is parallax not a good idea technique for determining distances of stars that are far away?
Distances are too far for it to be effective.
Is a star with no parralex very close to earth?
No. A star with no visible parallax is far away.
What does the angle of parallax determine?
Accuracy of readings of e.g. meters and certain optical instruments. Parallax is also used in astronomy for calculating distances to(astronmically)far-away objects.

Stars with large parallaxes are closer to Earth, while stars with small or undetectable parallaxes are further away.
Parallax cant be used on a star if the star is too?
We can't use parallax to measure a stars distance from the Earth if the star is already too far away. The angles used in parallax measurment are already very small, and if the star is beyond a certain distance from us the angle becomes too small to measure, and no distance can be determined.To date the largest distance that can be measured using parallax, with the Hipparchos sattelite, is about 1 600 light years. This will be improved with the European Space Agencies Gaia mission in 2012 and 2013.
What isTrigonometic parallax used to obtain distance to?
parsecs and arc seconds of one parallax to the distant background stars. it doesnt work very well across the intergalactic medium because there are no background stars outside of galaxies, so it mostly works to determine very far away distances within a galaxy or galaxies

What is a parallax and what is it used for?
parallax is a planet
How or with what do people measure a light year?
This can't be measured directly (as in, applying a measuring stick), so the distances are calculated in other ways. Several methods are used; for a start, for nearby stars, the star's parallax is measured. The smaller the parallax, the farther away the star is. Parallax is the apparent change in position, of a star, compared to the far-away background, as Earth moves from one side of its orbit, to the other.This can't be measured directly (as in, applying a measuring stick), so the distances are calculated in other ways.
