Its not the angular speed, but a phase shift that I was talking about.
Measurements of Earth's acceleration show that we are accelerating towards the Sun's current position (to the precision of the instruments), not its position 8 minutes ago.
If the acceleration isn't directly in line with the center of mass, then there will be an an angular acceleration component, which is bad news.
PS:
The center of mass is not 6 cm from the center of the sun, but about 500km according to some quick math.
1 AU makes for a very long lever
