Orientation of the Earth, Sun and Solar System in the Milky Way

[QUOTE="Dahook4444, post: 5865562"] One thing is very clear we are still not sure about the Structure of the Milky-way as no one has ever seen it from outside (see http://www.skyandtelescope.com article Seeing Far side of Milky Way) Two spiral arms or Four? Gaia Mission also raises interesting questions about the trajectory of stars. Stars primary motion around the Galaxy would seem to be the result of the rotation of the Spiral arms in which they reside. The Gaia mission on the other hand would suggest that all stars have a secondary orbital trajectory within their host spiral arm i.e. Sun's 70 million year declination cycle. The apparent erratic trajectory of some stars would suggest collisions are probable so Solar system not closed and some researchers believe our Solar system is a "fruit salad" of captured planets and Red dwarf stars (Velikovsky). That would certainly better explain Venus environment than "Greenhouse warming". [/QUOTE]
