Quizplus · Accepted Answer

Increasing the size of Earth's orbit would increase the baseline for measuring parallax, making it easier to detect. This is because the apparent shift in a star's position due to parallax is proportional to the baseline length. Speeding up or slowing down Earth's rotational motion or precession of its axis would not affect the baseline, and getting away from streetlights would improve the quality of observations but not make parallax easier to detect.
