Hi Andrew, I've been following this story for a few weeks now and have
a couple of questions I can't seem to get an answer for.

What is the average density of of this cloud?

What is the majority of the dust made of?

What velocity are the particles in the cloud traveling at relative to
us?

What will happen to the heliopause and the termination shock? will
they change shape or reduce in size?


When I look at the SOHO site I get information like this,

Current solar wind velocity 551 km/s

Current density 5.90 p/cm^3

400-800 km/sec electron-proton plasma velocity


What is the density of our solar system out at the heliopause?
