## Homework Statement

A photon is emitted at an angle \theta' by a star (system K') and then received at an angle \theta on Earth (system K). The angles are measured from a line between the start and Earth. The star is receding at speed v with respect to Earth. Find the relation between \theta and \theta'; this effect is called the

*aberration of light*.

## Homework Equations

## The Attempt at a Solution

I already read the Wikipedia article so DO NOT just post a link.

This is a special relativity question but I do not understand how you can answer it without GR. In special relativity, either theta=theta'=0 or theta is not 0 and the photon misses the earth.
