What is the definition of a parallax?

• The change in color of an object when viewed from different angles.

• The process of measuring the distance between two objects in space.

• The phenomenon of objects appearing larger when viewed from a closer distance.

• The apparent shift in the position of an object when viewed from different angles.

During a stargazing night, Liam, Arjun, and Grace were discussing how parallax is used in astronomy. Can you help them understand its application?

• Parallax is used to study the composition of planets.

• Parallax is used to determine the age of stars.

• Parallax is used to measure the distance to nearby stars.

• Parallax is used to measure the size of galaxies.

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
