[Problem] What I see change when traveling !!!

[pk]

Example. I'm going to the moon. When I leave earth influence and enter sun influence prograde become retrograde and I'm not facing the same part of the sky. It's hapen everytime when I'm changing influence planet....
Is it normal? I have never notice that before. Same thing on orbiter 2010-P1 or my old 2006-P1
Somebody else has this problem
Thank's

I know, it happens, it's weird, and I have no idea what could cause it...

It is pretty much normal in some situations. Earth moves around the sun at 29 km per second. If you leave Earths sphere of influence, your velocity vector is relative to the sun so the 29 km/s of Earth are added to your previous one - and could mean easily that you are suddenly pointing retrograde, against your direction of travel relative to the sun, while still flying away from Earth.

so that's the answer. Thanks.

Now to figure out how come I didn't think about this myself...
