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 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.
Method to measure the distance to nearby stars directly?
For nearby stars, the parallax method gives the most accurate measure of distances.For nearby stars, the parallax method gives the most accurate measure of distances.For nearby stars, the parallax method gives the most accurate measure of distances.For nearby stars, the parallax method gives the most accurate measure of distances.
What was ptolemy's explanation regarding the parallax of stars?
Ptolemy believed that the lack of observed annual parallax in stars was because they were extremely far away, beyond the distance that could be detected by the naked eye at the time. This led him to support the geocentric model where Earth was at the center of the universe.
How does parallax shift varies with distance?
The parallax shift decreases as distance increases. Objects that are closer to an observer will have a larger apparent shift in position when the observer changes their viewing angle, while objects that are farther away will have a smaller apparent shift in position. This difference in the amount of shift is what allows astronomers to use parallax to calculate the distances to nearby stars.
What can parallax be used to determine about a star?
Parallax is a method used to find the distances of stars.
What is the apperent movement of stars called?
parallax
Which stars have the largest parallax angles-?
the stars nearest Earth

What is most useful in determining the position of stars?
parallax
What can distances to nearby stars determined by?
Stellar parallax
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.
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).
What is the apparent shift of stars as earth orbits the sun?
parallax :)
What is Often used to determine the distance to nearby stars?
parallax
What is measure of the amount of a stars light received on earth?
