When we check for Stellar Parallax, we do not detect any parallax at all, and no evidence that the Earth moves even an inch, particularly when considering Polaris's fixed position, let alone 200 million miles every 6.66 days, as it allegedly shoots out in four opposing vectors of motion, including allegedly spinning at 1000 mph in an Outer Space vacuum while orbiting The Sun at 66,600 mph (They just love that number, 666.), and while our solar system shoots out at 821,000 kph, and while circling an imaginary Super Massive Black Hole at the center of The Milky Way Galaxy at millions of miles per hour. Hence, certain Jesuit Catholic Priests, in order to salvage the Heliocentric wreck they had created in the 15th century, came up with the idea that the Stars, therefore, must be unimaginably far, far, far away....so far away that The Constellations remain immutable, exactly fixed, and unchanging, century after century. And so, they had to invent Light Years, one Light Year being the distance light would travel in one year. This invention placed the Stars so far away that even if the Earth moves 200 million miles in 6.66 days, there will be no observable Stellar Parallax.
