Traditional tools like radar are ineffective due to energy loss over vast distances. Instead, they use stellar parallax, which involves measuring a star's apparent shift against distant stars as Earth orbits the Sun. This method helps in calculating distances to nearby stars, similar to perceiving the shift of a finger when viewed from different angles.
