Which of the following statements about parallax is not true? A You can demonstrate parallax simply by holding up a finger and looking at it alternately from your left and right eyes. B The existence of stellar parallax is direct proof that Earth orbits the Sun. C Measurement of stellar parallax allows us to determine distances to nearby stars. The technique of stellar parallax was used by Hubble to determine that the Andromeda Galaxy (M 31) is about 2 million light-years away. Ancient astronomers were unable to measure parallax and used the absence of observed parallax as an argument in favor of an Earth-centered universe. D

Distances to the nearest stars (up to 500 by away) can be measured by a technique called parallax, as shown in Figure 34.26. What are the angles 1 and 2 relative to the plane of the Earth’s orbit for a star 4.0 by directly above the Sun?
Why did Tycho Brahe expect the new star of 1572 to show parallax? Why was the lack of parallax evidence against the Ptolemaic model?
Explain how parallax measurements can be used to determine distances to stars. Why can we not make accurate measurements of parallax beyond a certain distance?
The apparent change of the position of a star due to the Earths orbiting the Sun is called ___. (18.1)
Construct Your Own Problem Consider a star moving in a circular orbit at the edge at a galaxy. Construct a problem in which you calculate the mass of that galaxy in kg and in multiples of the solar mass based on the velocity of the star and its distance from the center of the galaxy. Figure 34.26 Distances to nearby stars are measured using triangulation, also called the parallax method. The angle of line of sight to the star is measured at intervals six momma apart, and the distance is calculated by using the known diameter of the Earth's orbit. This can be done for stars up to about 500 ly away.
16. Today, astronomers can detect and measure stellar parallax for thousands of the nearest stars, providing us with direct evidence that Earth really does orbit the Sun. Moreover, these measurements allow us to calculate distances to these relatively nearby stars. If we hope to use parallax to measure distances to even more-distant stars, which of the following telescopes would be most useful?
1.) How far, in parsecs, is an object that has a parallax of 1 arc second? How far is it, in light years? 2.) How far in parsecs, is an object that has a parallax of 0.1 arc-seconds? How far is it, in light years?
1. For an observer located on the equator, the altitude of the stars due West will... A) increase and decrease B) decrease C) increase
6) Using parallax from the ground to determine the distances to stars becomes impossible due to atmospheric disturbances at a distance of about: a. 10 parsecs b. 100 parsecs c. 500 parsecs d. 60 parsecs e. 2 parsecs
(Astronomy) PSR1913+16 Problem III. As the shape of the graph shown is not skewed, the orbit can be assumed circular. Also assume the system is viewed edge-on (that is, the orbital system is not inclined to the observer). Using these assumptions, the maximum radial velocities, and the orbital period T = 7.75 hours, find the orbital radii of the stars from the center of mass. (Hints: The figures below may be helpful. Use v = 2πr/P, where v is velocity, P is period, and r is radius. Note: redshifts have positive radial velocities values in the upper figure, whereas blueshifts have negative radial velocity values.)
"51 Pegasi" is the name of the first normal star (besides the Sun) around which a planet was discovered. It is in the constellation Pegasus the horse. Its parallax is measured to be 0.064 arcsec. a. What is its distance from us? b. The apparent brightness is 1.79 × 10-10 J/(s·m2 ). What is the luminosity? How does that compare with that of the Sun? Look up the temperature: how do
If you place your index just in front of you and try to look at it with you right eye open and your left eye close, then look at it with your left eye open and right eye close this time. You will notice that there is a slight change of the position of your index finger. What concept is applied how astronomers were able to measure the distance of heavenly bodies from the Earth? * A.
