Larger parallax means smaller distance
Historical Attempts to Detect Astronomical Parallax
Historically - Solar Sytem ObjectsWe how know that the measurement of the parallax of objects in the Solar System is hampered by the vast distances (hence small parallax angles) invloved. Furthermore, of course before the first telescopes were invented (c.1600), all observations were performed using the naked-eye.
Historically - The Stars...We how know that the measurement of the parallax of the stars is hampered by the vast distances (hence small parallax angles) invloved. In addition, there are the effects of
However equally important to appreciate is that the search for parallax was key to put a scale on the Copernican system (c.1541) of the universe (still is some doubt in the early 1600s).
