What else can I help you with?
What can parallax be used to determine about a star?
Parallax is a method used to find the distances of stars.
Which stars have the largest parallax angles-?
the stars nearest Earth
What is the apperent movement of stars called?
parallax
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
Is spectroscopic parallax is more accurate than trigonometric parallax for measuring nearby stars?
Spectroscopic parallax is generally less accurate than trigonometric parallax for measuring distances to nearby stars. Trigonometric parallax directly measures the star's slight apparent shift against background stars, providing a precise distance calculation. Spectroscopic parallax, on the other hand, relies on the star's spectral characteristics and assumptions about its intrinsic brightness, introducing uncertainties.
What effects doe lengthening the distance from the observer have on parallax?
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.
Parallax would be easier to measure if?
Parallax would be easier to measure if the Earth were farther from the sun. This way, there will be a wider angle to the stars using the parallax method.
What is most useful in determining the position of stars?
parallax
What can distances to nearby stars determined by?
Stellar parallax
Is parallax a star?
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).
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.
What is the apparent shift of stars as earth orbits the sun?
parallax :)
