Voyager 2's Direction & Journey Through Space

[lifeonmercury]

I've been reading that Voyager 2 is scheduled to pass by Sirius in about 300,000 years. Other sources state it is destined to orbit the Milky Way for billions of years. I don't understand how it can be headed toward a specific direction and orbiting the center of the galaxy at the same time.

Maybe because Sirius is orbiting the galaxy?

It is heading in some direction relative to the sun. Relative to the overall motion of the Sun, Sirius and Voyager 2 around the galactic center its speed (relative to the sun) is negligible, we all orbit the galaxy in similar orbits.

Or to put it differently, when I went cycling across Europe last autumn, I was scheduled to pass London within two weeks. Other sources stated that I'm destined to orbit the Sun for many years still (and it's too early for a middle age crisis ).
