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?
Nearby stars have a larger parallax angle.
What is a stars parallax?
The parallax refers to the apparent change in the star's position, due to Earth's movement around the Sun. This parallax can be used to measure the distance to nearby stars (the closer the star, the larger will its parallax be).
Why does the parallax method of measuring star distances require observations of a star six months apart?
Because that is the entire idea of the parallax method - get measurements from two points, as far away as possible.It would be possible to do measurements a month apart, for example, or a week apart; but that would give a smaller parallax angle, and thus a larger error.Because that is the entire idea of the parallax method - get measurements from two points, as far away as possible.It would be possible to do measurements a month apart, for example, or a week apart; but that would give a smaller parallax angle, and thus a larger error.Because that is the entire idea of the parallax method - get measurements from two points, as far away as possible.It would be possible to do measurements a month apart, for example, or a week apart; but that would give a smaller parallax angle, and thus a larger error.Because that is the entire idea of the parallax method - get measurements from two points, as far away as possible.It would be possible to do measurements a month apart, for example, or a week apart; but that would give a smaller parallax angle, and thus a larger error.
If a star has a parallax of 0.20 arc seconds what is the distance to that star?
I assume you mean the parallax. If the parallax is 0.1 arc-seconds, then the distance is 1 / 0.1 = 10 parsecs.I assume you mean the parallax. If the parallax is 0.1 arc-seconds, then the distance is 1 / 0.1 = 10 parsecs.I assume you mean the parallax.

How far is the star eltanin?
About 154 light-years.

Nearby stars have a larger parallax angle.
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.
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.

Star distance measured by what?
depends who's measuring and which star. it is a matter of preference. 1. kilometers/miles - relatively nearby star like our sun 2. lightyears - near-medium star like the nearest star except the sun 3. parsecs - medium-far star 4. megaparsecs - very far star there are some others but they are not the usual ones
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 do you use to measure the distance to far away stars?
Light years, parsecs, and kiloparsecs. Light years and parsecs are used to measure distances between neighbouring star system's, kiloparsecs are used to measure distances within a galaxy.
