This was one of the major achievements of Einstein's 1905 Special Relativity mathematics.

Aberration [ aberration of (star)light, astronomical aberration, stellar aberration ]: An astronomical phenomenon whereby small apparent motion displacements of all fixed stars on the celestial sphere due to Earth's orbital velocity mandates that terrestrial telescopes must also be adjusted to slightly different directions as the Earth yearly transits the Sun.

For example, vertically falling rain upon your umbrella will appear to come from in front of you the faster you walk and hence the more you will have to adjust the position of the umbrella in order to deflect the rain.
