Which of the following statements about stellar parallax is true?
- The amount of parallax we see depends on how fast a star is moving relative to us.
- The closer a star is to us, the more parallax it exhibits.
- It takes at least 10 years of observation to measure a star's parallax.
- We observe all stars to exhibit at least a slight amount of parallax.
- Stellar parallax was first observed by ancient Greek astronomers.

Answer :

Answer:

The second option : The closer a star is to us, the more parallax it exhibits.

Explanation:

When a star is close to the observer, it is possible to better see the difference in movement and distant because of space behind or other stars close to it, so we can measure distances from these celestial bodies by using parallax. Just as trees seem to move more than the mountains in the background during a car trip, so do stars, but in a much more imperceptible way. The closer to the viewer the more parallax will display.
