Proving that CW Leonis is moving toward to our solar system over 30 years

Thx i forgot about that one! I remember it now that you mention it... That one is very important too because it would probably dictate the speed of our solar system relative to the rest of our galaxy.

And our Solar System may be moving at a faster rate.! Relative to the Galaxy! Or parts of it.

Our solar system oscillates up and down it's orbital plain around the galaxy. That would be where the only speed discrepancy would come from relative our galactic neighborhood. Because rotational speed in the Milky Way is governed by how far away from the center you are. If we keep up with the hood, going up and down too, then we must be traveling a bit further distance in the same amount of time.

Unless it has stopped, it could be even closer.

It's called better measurements today than in the 60's. That makes a LOT more sense than claiming it's traveling towards us many times the speed of light.

I see that our solar system is moving towards Leo at a speed of about 872405 MPH. Maybe we're moving towards each other. www.scientificamerican.com...

CW Leonis has a radial velocity with respect to the sun of −18.6 km/s (Ladjal, et al 2010 Astronomy&Astrophysics - yes you need journal access to get it or you need to pay for it - yes I have journal access - no I'm not going to give you an illegal copy of the journal and break copyright law - this is directed to no one in particular, but before you ask... the answer is no) . Given a distance of about 135 parsecs, even if CW Leonis were on a collision course (it's not) with our solar system, it would take over 7 million years to get here.
