What is stellar parallax and how is it used to determine the distance to stars? Stellar parallax measurements are used in astronomy to determine which properties of stars? You measure the parallax angle for a star to be 0.1 arcseconds. The distance to this star is? What is stellar parallax caused by? What properties of stars are stellar parallax used to measure? How could an observatory on Mars would improve stellar parallax measurements? What would be the advantages of measuring stellar parallaxes from Mars rather than from Earth? Why does stellar parallax exist? We can't detect stellar parallax with naked-eye observations. What makes parallax easier to observe? Why do stellar parallax measurements work only with relatively nearby stars? Can we can measure stellar parallax for most stars in our galaxy? How is parallax calculated? Why do astronomers try to find the distance to stars using parallax? A particular star is found to have a stellar parallax of 1/6 arcsec. What is the distance to this star? What does it mean if the the stellar parallax of a star is too small to be measured? How long is the baseline in measuring stellar parallax? What is the most accurate way to determine the distance to a nearby star? How do astronomers use stellar parallax? How does stellar parallax depend on distance?

What does stellar parallax prove? What makes stellar parallax easier to observe? Why is stellar parallax important? Why does stellar parallax occur? What is a parallax angle? How can you find the parallax angle of a star? What is the general defination of parallax? How does distance affect stellar parallax? Would it be easier to measure a stars parallax from Pluto? Why? Would it be easier to measure a stars parallax from Jupiter? Why? Would it be easier to measure a stars parallax from Mercury? Why? Would it be easier to measure a stars parallax from Ceres? Why? Would it be easier to measure a stars parallax from Neptune? Why? Would driving in a car and comparing two objects as you're moving be an every day example of a parallax? How would you use the parallax formula to calculate the distance to each of the following stars? Sirius has a parallax of 0.377 arc seconds. How far is it away? If a star's parallax angle is too small to measure, what can you conclude about the star's distance from Earth? Do astronomers use steller parallax to measure the distance to stars? Did the lack of observable parallax help convince astronomers Earth did not move? Which star is closest, A or B? Star A has a parallax of 0.005 arcseconds and Star B has a distance of 500 parsecs. What are the advantages of parallax? What are the disadvantages of parallax? How would you use the parallax formula to determine the distances to a star (in parsecs)? The parallax angle is 0.0012516. How would you use the parallax formula to determine the distances to a star (in parsecs)? The parallax angle is 0.002790.

The star Wolf 1061 has a parallax of 2.34 arcseconds, while the star Ross 652 has a parallax of 1.70 arc seconds. What can you infer from this information? How are parallax and distance related? How do astronomers use parallax to study stars? Who is the scientist who discovered parallax? What is a parallax error? If a certain star displayed a large parallax, what could you say about the star’s distance from earth? If a certain star displayed a small parallax, what could you say about the star’s distance from earth? A star has an apparent magnitude of 10 and an absolute magnitude of -5. How far away is it?
