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).

Which star would have a greater parallax the earth or the arcturus?

Earth isn't a star and doesn't (can't) have a parallax, becuse we use Earth's orbit as a baseline to measure parallax.


What can parallax be used to determine about a star?

Parallax is a method used to find the distances of stars.


What does a big parralax say about a stars distance?

The larger a star's parallax, the closer the star is to us.


Parallax can't be used on a star if the star is too?

Close.


How do scientists determine the parallax of a star?

they look at the star in, say, spring, then fall or summer then winter. we have to be on opposite sides of the star to see the parallax, so it takes about a year


What two words are the abridgement for a parsec?

parallax second When we observe a star from opposite ends of the Earth's orbit, if there is a parallax difference of 1 arc second, that star is 1 parsec away.


A star has a parallax of 0.75 of arc How far away is this star in light years?

The distance to the star can be calculated using the parallax angle (in arcseconds) and the formula: distance (in parsecs) = 1 / parallax angle (in arcseconds). Given a parallax of 0.75 arcseconds, the star is approximately 1.33 parsecs away. Converting parsecs to light years (1 parsec ≈ 3.26 light years), the star is about 4.34 light years away.


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.


How is the distance to a star determined using the measure of parallax?

The distance to a star can be determined using the measure of parallax by observing the star from two different points in Earth's orbit around the Sun. By measuring the apparent shift in the star's position against more distant background stars, astronomers can calculate the star's distance based on the angle of the parallax.


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 angle is too small to measure what can you conclude about the star's distance from earth?

It means that the distance is greater than a certain amount - depending on how precisely you can measure the parallax.
