Avery, Laveah, and Ky are stargazing and discussing how astronomers measure the distance to stars. They come up with different ideas. Which method correctly describes the use of parallax to measure the distance to stars?
Avery suggests analyzing the star's composition
Leveah thinks it's by measuring the brightness of the star
Ky believes it's by observing the apparent shift in the position of a star when viewed from different points in Earth's orbit around the Sun
They all agree on using a telescope to directly measure the distance
How does parallax change as the distance to the object increases?
fluctuates
remains constant
increases
decreases
Marqueeze, Jalen and Alyssa are stargazing and discussing parallax. They wonder why parallax is only useful for measuring distances within a certain range. Can you help them understand?

Parallax is only visible at close distances.
Parallax is not accurate for measuring long distances.
Parallax is only applicable to objects within a limited range.
