Reply to comment by Aseyhe in How fast does the Milky Way spin? How far does Earth move through space in a year? by Sabre-Tooth-Monkey

>Interestingly, that motion is anti-aligned with our motion about the galaxy, which means the Milky Way itself is moving at about 550 km/s with respect to the CMB.

So, given enough time for the sun to finish swinging around to other side of its orbit, will its net velocity WRT the CMB be ~150km/s?

The opposite: since we are currently moving (with respect to the CMB frame) slower than the galaxy by about 180 km/s, in half a galactic year we should be faster than the galaxy by about the same, achieving about 730 km/s.
