According to the Helical model, as the Sun orbits around the galaxy, the planets that orbit the sun are travelling perpendicular to the path of the Sun. This is better shown in this video:

My question is, which pole on Earth faces in the direction that the Sun moves? The South Pole or the North Pole?

  • $\begingroup$ @RobJeffries I am sure your answer is absolutely correct, but I still have a hard time getting everything straight in my head. Does it mean that if I stood at about 30 degrees North latitude that once a day the Sun's direction of motion wrt the galaxy would be straight overhead? $\endgroup$ – uhoh Dec 18 '18 at 3:16

    $\begingroup$ The YouTube video referred to in the OP is full of nonsense and has been widely debunked. $\endgroup$ – Rob Jeffries Dec 18 '18 at 7:14
