Question

The Earth is revolving around the Sun at approximately 67,000 mph. We are travelling on a "Merry go Round" throughout space! When we want to find the distance we are away from stars, it's important to remember frame of reference! Astronomers will take a picture of a star, wait 6 months, and take another picture from the same location. The difference in angle gives us the distance! Stars with a greater angle are much closer to us than stars with lesser angles, which are much further away. This scenario is an example of what?

Answer 1

The scenario you described is an example of **Parallax**. This method involves observing the apparent shift in position of a nearby star against the background of more distant stars due to the change in the observer's position (in this case, Earth's orbit around the Sun). The greater the angle of parallax, the closer the star is to Earth.
