Stellar parallax was first observed by ancient Greek astronomers. O C. The amount of parallax we see depends on how fast a star is moving relative to us. D. It takes at least 10 years of observation to measure a star's parallax. OE. The closer a star is to us, the more parallax it exhibits.
Stellar parallax is used as a tool to determine distances to stars. Describe how stellar parallax works. Also discuss the limiting factors in its use and the maximum distance that can be accurately measured using this technique.
