Aberration Of Starlight

displacement of the apparent path of light from a star, resulting in a displacement of the apparent position of the star from its true position; ...
aberration of starlight
The difference between the observed position of a star and its true direction; this is a combined result of the observer's motion across the path of the incoming starlight and the finite speed of light.

Aberration of Starlight The apparent displacement of a star's position as a consequence of Earth's motion through space and the finite speed of light. More here.
Direct evidence for this was obtained only in the early eighteenth century, when astronomers discovered the aberration of starlight"a slight (20" ) shift in the observed direction to a star, ...
In attempting to find stellar parallax, the annual shift in stellar position caused by the shifting position of the orbiting Earth (from which we get stellar distance), in 1728 James Bradley discovered in "aberration of starlight, ...
But the observational evidence of the time favoured the epicycle-based Ptolemaic system. The Copernican system was promoted by some but it was the discovery of the aberration of starlight in 1728 that proved without doubt that the Earth orbits the ...
