Stellar parallax is a method used by astronomers to measure the distance of nearby stars. It works by observing a star from two different points in Earth's orbit around the sun and then measuring the angle of displacement.

1. The first reason for a maximum distance is due to the limitation of our observation technology. The angle of displacement becomes smaller as the distance to the star increases. At a certain point, this angle becomes too small to measure accurately with our current technology.

2. The second reason is due to the nature of space itself. Space is not completely empty, but filled with interstellar medium - dust and gas that can distort the light from distant stars. This distortion can make it difficult to accurately measure the angle of displacement for very distant stars.

3. Lastly, the movement of other stars can also affect the measurement. All stars, including our sun, are in motion. This motion can cause the position of distant stars to change relative to us, which can affect the measurement of the parallax angle.

In conclusion, while stellar parallax is a powerful tool for measuring the distance of nearby stars, it has limitations due to our current technology, the nature of space, and the motion of stars.
