Relativity
Bradley's aberration is visible from every object in the Universe, not just the earth. The surface of the sun is too hot for an observer to stand on. The paths of the stars are shown in the article as straight lines, ellipses and circles, but these are over-simplifications. Actually, the paths are irregular. A hypothetical observer on the surface of the sun would see the effect of Bradley's aberration. Over-simplifications introduce falsehood, which should play no part in science. The irregular paths might cross at times, but they do so at irregular intervals, which continuously change. The same mistake was made with the precession of the equinoxes. It is now said to follow an irregular path, not a circle, with no fixed period. The phrase "The earth goes round the sun" was thought to mean something before the introduction of the theory of relativity. It is now said to be meaningless. The aberrations seen from the earth and the sun only prove that the two objects are moving relative to one another. Buluu221 (talk) 13:14, 14 January 2023 (UTC)
 * See Axial precession.
 * See Values.
 * There is a small, roughly but not exactly annual, component in the aberration visible from the sun, caused by the earth's gravitational attraction on the sun. There is also a small component in the aberration seen from the sun caused by Mercury's gravitational on the sun.

This component caused by Mercury does not mean that the sun is going around Mercury, only that the sun and Mercury are moving relative to one another. The component in the aberration seen from the sun caused by Mercury has a rough but not exact, constantly changing, period of 88 days.
