The Earth is moving around the Sun at around 30km/s, a change of 60km/s over the course of the year.
- Presumably, measurements of the speed of light would show a redshift up to ±30km/s? Are redshift measurements this accurate?
- Likewise, the speed of the Solar System around the Milky Way, is estimated to be about 230 km/s, and the Milky Way is moving at some speed through the universe. Do these need to be these factored into redshift measurements?
