Earth travels 300 million kilometers in one year.Or 2 astronomica units.

Parallax and distance are related through trigonometry. The closer an object is to the observer, the greater its parallax shift when viewed from different positions. By measuring this shift and knowing the distance between the observer's positions, the distance to the object can be calculated using trigonometric principles.
